Wooden skirting boards, architraves, and cornices: complete room finishing

There comes a moment in renovation when the walls are painted, the floor is laid, the furniture is arranged — yet the room still looks unfinished. Something is off. Something is missing. The eye wanders and finds no point of focus. An experienced designer at such a moment will say one word: trim.

Wooden baseboardBaseboard, casing, cornice, molding — this is the room's 'frame.' They delineate space, separate planes, and create architectural rhythm. Without them, a room is just four walls with a floor and ceiling. With them — it's an interior with character, style, and internal logic.

This article is a detailed guide to the entire wooden trim system for a complete room renovation. Not just one element, but all at once: baseboard, casing, cornice, molding — in a unified system, with specific examples, calculations, and links to a real catalog.

What is wooden trim — baseboard, casing, cornice, molding as a unified system

Watch video ...

Trim: definition and architectural role

Trim — from the term 'linear meter' — refers to longitudinal profiled products made of wood (or other materials), used for finishing linear transitions and joints in interiors. The word is prosaic, almost technical. But behind it lies the entire history of European architecture: no classical interior from antiquity to Art Deco was complete without a system of profiled wooden elements.

Wooden trim is divided into four main groups by application area:

• Baseboard — the transition from floor to wall (floor) or from wall to ceiling (ceiling)

• Casing — framing for a door or window opening

• Cornice — a decorative element at the junction of wall and ceiling, often with a curtain rod function

• Molding — a narrow profiled strip used for wall decoration, creating panel molding, and finishing furniture fronts

All four groups are interconnected: they 'speak' the same language of profiles, and this creates interior unity. The baseboard in the lower register 'responds' to the cornice in the upper. The casing 'rhymes' with the molding of a wall panel. The profile system is the grammar of space.

Why a single source is important

When all trim elements are ordered from one manufacturer — from the same wood species and the same profile series — the interior achieves that architectural integrity otherwise unattainable. Wood from the same batch of kiln drying has a uniform natural tone. Coating from the same can of oil or varnish completes the unity.

In the STAVROS catalog, the entire K-serieswooden trim— over 30 profiles — is made from solid beech and oak. This is a unified production system where baseboard K-006 and cornice K-070 are made on the same equipment, from the same wood species, with identical finishing quality. That's why a complete order from STAVROS is not just convenience, but a guarantee of a unified result.

Ornamental language: how profiles 'speak' to each other

Each profile has an 'ornamental level' — the degree of decorative saturation in its cross-section. From minimal (a straight rectangle) to maximal (multi-level with floral, geometric, and classical elements).

Rule of uniform ornamental level:

• Modern interior: all elements — ornamental level 'minimum'

• Neoclassical: 'moderate' — with one or two decorative elements in the profile

• Classical: 'saturated' — with several decorative levels

• Baroque, Empire: 'maximum' — with a rich, sculptural character of the profile

Do not mix: a minimalist baseboard with a rich Baroque cornice — this is an ornamental conflict that is felt immediately, even by people without specialized education.

Wooden floor and ceiling skirting boards — profile selection

Floor skirting board: the logic of the lower zone

Wooden baseboardThe floor skirting board is the most 'loaded' element of the trim system. It operates in the lower zone of the room, taking impacts from furniture, exposure to wet cleaning, and mechanical contact with vacuum cleaners and brushes. At the same time — it is the first thing noticed when entering a room, because the lower zone is what the eye reads as a person moves.

Choosing the height of the floor skirting board is one of the key proportional decisions in interior design:

40–60 mm skirting board — concise, receding into the background. For modern interiors, minimalism, Scandinavian style. Does not accentuate the lower zone, 'frees' the eye for other elements.

70–90 mm skirting board — the 'golden mean'. Moderately noticeable, creates a clear demarcation between floor and wall. Universal: works in both modern and classic interiors.

100–150 mm skirting board — decoratively significant. Creates a visual 'plinth' for the wall. For classic, Empire, Baroque interiors with ceilings from 2.8 m.

160 mm and above skirting board — monumental. Architectural 'plinth' of a high level. For formal rooms, mansions, spaces with ceilings of 3.2 m and more.

From the STAVROS K-series catalog: K-034 (from 230 rub./lm) — minimalist 40 mm, K-006 (from 440 rub./lm) — moderately classic ~60 mm, K-070 (from 950 rub./lm) — rich ~80 mm, K-009 (from 1,420 rub./lm) — opulent classic ~90 mm, K-018 (from 1,630 rub./lm) — ~100 mm, K-066 (from 2,580 rub./lm) — ~120 mm, K-104 (from 6,060 rub./lm) — flagship ~150 mm.

Ceiling skirting board: the logic of the upper zone

Ceiling skirting board — coving, cornice, ceiling molding — conceals the transition from wall to ceiling. Unlike the floor skirting, it is located 'overhead' and is perceived differently: not in motion, but in a state of rest, when the gaze rises upward.

Proportional rule for ceiling skirting board:

• Ceiling 2.5 m → skirting board 60–80 mm

• Ceiling 2.7 m → skirting board 80–100 mm

• Ceiling 3.0 m → skirting board 100–130 mm

• Ceiling 3.5 m and above → skirting board 130–200 mm

From the K-series for ceilings: K-034 and K-125 — for 2.5 m ceilings in modern style; K-006, K-016, K-071 — for 2.7–3.0 m; K-009, K-018, K-066, K-104 — for 3.0 m and above in classic interiors.

Floor and ceiling: should they match

Classic rule: floor skirting board = ceiling skirting board × 1.2–1.5. That is, the floor skirting is slightly taller than the ceiling one. This is related to visual 'weight': the lower zone should visually be heavier than the upper one — this creates a sense of stability.

Modern approach allows inversion: ceiling skirting board larger than floor one — to create an effect of 'suspended' space. Used in minimalist interiors with light walls and dark floors.

When ordering a set from one K-series, both skirting boards are automatically in a unified ornamental style — whatever you choose.

Wooden architrave — door opening trim

What is an architrave and why it is indispensable

Wooden architrave — a profiled strip framing a door or window opening. Conceals the technical gap between the door frame and the wall (reveal), creates a decorative 'frame' for the opening.

A door opening without an architrave is a break in the trim system. The wall 'ends' at the opening and lacks decorative completion. This is especially critical in classic interiors: there, the architrave is a full-fledged architectural element, sometimes more significant than the door itself.

STAVROSArchitraves from the trim seriesare selected from the same K-series profiles as the skirting board. This is fundamental: an architrave from the same profile as the skirting board — architectural unity. An architrave 'from a store' next to a K-series skirting board — guaranteed ornamental conflict.

Architrave construction: three parts

A classic door architrave consists of three parts:

Vertical posts (pilasters) — run along the sides of the opening from the floor to the horizontal crossbar. Height: from floor to lintel + 10–20 mm gap to the top crossbar.

Horizontal crossbar (frieze, head casing) — runs along the top of the opening. Width: opening width + 2 × width of vertical stiles.

Corner blocks — decorative square elements at the corners where vertical stiles and horizontal crossbars meet. Used in classic interiors to create an 'architrave' look for the casing. They eliminate the need for complex 45° miter cuts at the corners.

In the STAVROS K-series, corner blocks can be custom-made — a square element made from the same oak or beech, with a width equal to the profile width of the casing.

Casing width: from narrow to wide

Casing width — a parameter that defines the 'weight class' of the framing:

Narrow casing 40–60 mm — delicate, almost unnoticeable. For modern interiors. Profiles K-034, K-125.

Medium 70–90 mm — expressive, but not dominant. Classic for contemporary interiors. Profiles K-006, K-016.

Wide 100–130 mm — 'architrave-like', significant. For classic interiors. Profiles K-070, K-071, K-009.

Extra-wide 140 mm and more — monumental. For formal spaces. Profiles K-018, K-066, K-104.

Casing and baseboard: the principle of parallelism

The ideal option: the casing and floor baseboard have the same profile. Then the vertical lines of the casing 'continue' the horizontal line of the baseboard in a unified ornamental key. This is called the principle of profile parallelism.

Practical implementation: buy a K-006 wooden baseboard + casings from the same K-006. One purchase — a complete ensemble of all vertical and horizontal framings in the room.

Window casing: specifics

Window casing differs from door casing: it frames not only the side and top reveals but also the bottom one — the windowsill. The bottom casing in this case is a decorative strip that covers the joint between the windowsill and the wall.

From the STAVROS K-series, the narrow profiles K-034 and K-125 are optimal for window casing: they do not overload the window opening with decoration while clearly outlining the reveals.

Wooden cornice — ceiling cornice and curtain cornice

Decorative ceiling cornice: the architectural 'crown'

A wooden ceiling cornice is a profiled strip mounted at the junction of the wall and ceiling. In architectural terminology — 'cornice' (from Greek korōnis — 'crown'). It finishes the wall from above, creating a 'cap' for the vertical plane.

The ceiling cornice is significantly richer in profile than the floor baseboard: it is the 'upper accent' of the room, viewed with an upward glance. This is why in classic interiors, the ceiling cornice is more complex and richer than the floor one.

From the STAVROS K-series:

• K-043 (from 870 rub./lm) — moderate ceiling cornice, neoclassical

• K-070 (from 950 rub./lm) — rich, for classic style

• K-071 (from 1,140 rub./lm) — opulent profile

• K-009 (from 1,420 rub./lm) — expansive classic

• K-018 (from 1,630 rub./lm) — monumental

• K-066 (from 2,580 rub./lm) and K-104 (from 6,060 rub./lm) — top tier for formal rooms

Composite cornice: when one profile is not enough

In formal interiors with high ceilings (3.0 m and above), a composite ceiling cornice is used — a combination of two or three profiles mounted in steps from the wall to the ceiling. This is the most accurate reproduction of a classic architectural entablature.

Typical composite system:

1. Lower frieze: narrow straight profile K-034 — a horizontal 'shelf'

2. Medium profile: K-071 or K-009 — the main decorative element

3. Upper cornice: K-016 or K-043 — transition to the ceiling

This system creates a depth of 80–120 mm and a height of 200–300 mm — this is the level of a palace interior, achievable from the standard STAVROS molding range without custom plasterwork.

Wooden curtain rod: function + decor

A wooden curtain rod is a special type of ceiling cornice that combines decorative and functional roles: it has a curtain rod pipe or track mounting system built into it (or attached to it).

Structurally, it is a board 150–200 mm high, fixed horizontally to the wall just above the window opening. The front face is profiled. Behind it, the curtain track or curtain rings are concealed.

Advantages of a wooden curtain rod over a metal one:

• Decorative consistency with the room's molding (one profile, one wood species)

• Ability to paint in any color to match the interior

• Monumentality — a 'framed' window look with heavy curtains

From the STAVROS K-series: wide profiles K-018, K-009, K-066 — can be used as the front strip of a curtain rod when mounted on a special support block.

Wooden molding — where it is used and how to choose

Wooden molding: not just for pictures

The word 'molding' most often evokes associations with a frame for a painting or mirror. ButWooden Picture Framein interior design — it is a significantly broader concept. It is any narrow profiled strip used for decorative surface finishing.

Areas of application for wooden molding:

Molding panels on walls. A set of moldings forms rectangular or shaped 'frames' on walls — molding panels. This is a classic technique that reproduces the look of wall 'paneling' in 17th–19th century interiors. The panels divide the wall into 'fields' and create a rhythmic structure.

Furniture fronts. Molding is mounted on flat fronts of kitchen cabinets, wardrobe doors, cabinets — creating a framed look without replacing the fronts themselves. This is the cheapest way to turn flat laminate fronts into classic molded ones.

Ceiling coffers. A set of moldings forms a 'grid' on the ceiling — a coffered ceiling. The cells of this grid — the coffers — can be painted in a color contrasting with the main ceiling.

Inter-room transitions. Molding as a vertical decorative strip at the transition between walls of different colors — delineates planes without a casing.

Frames for mirrors and paintings. Classic application. In the STAVROS catalog, frames from theRM-series— over 30 profiles for mirrors and paintings.

Wooden molding profiles in the K-series

For the role of molding (narrow decorative strips) from the STAVROS K-series, the following are optimal:

• K-034 (from 230 rub./lm) — width ~40 mm, minimalist. For molding panels in a modern interior.

• K-105 (from 300 rub./lm) — ~45 mm, with a light classical element.

• K-125 (from 270 rub./lm) — ~40 mm, Scandinavian character.

• K-016 (from 610 rub./lm) — ~55 mm, moderately classical.

For furniture fronts and coffered ceilings — K-034 and K-105 as basic. For classical molding panels with ornament — K-016, K-006.

How to create a molding panel from wooden molding

A molding panel — a 'frame' on the wall — is created as follows:

1. Mark a rectangle of the desired size on the wall (typical: 400×600 mm, 500×800 mm or custom)

2. Cut four pieces of molding with 45° mitered corners

3. Mount with adhesive + finishing nails

4. Seal corner joints with acrylic sealant

5. Paint to match the wall color (then the panels create a 'relief' effect) or in a contrasting color (then — a clear pattern on the wall)

Molding consumption for one 500×800 mm panel: (500+800) × 2 = 2,600 mm + 10% reserve = ~3 linear meters. At a price of K-034 from 230 rub./linear meter — one panel costs ~700 rub. in materials.

Calculation: how to calculate the total linear footage of molding for one room

Calculation algorithm for a typical room

Consider a typical bedroom 4.0 × 3.5 m, ceiling height 2.7 m, one door 0.9 m, one window 1.4 m.

Floor skirting board

• Room perimeter: (4.0 + 3.5) × 2 = 15.0 linear meters

• Minus door opening: −0.9 linear meters

• Total net perimeter: 14.1 linear meters

• 10% cutting reserve: +1.4 linear meters

• To order: 16 linear meters

Ceiling baseboard / cornice

• Ceiling perimeter: (4.0 + 3.5) × 2 = 15.0 linear meters

• 10% cutting reserve: +1.5 linear meters

• To order: 17 linear meters

Door casing (on both sides)

• Two vertical posts on each side: 2 × 2.2 m = 4.4 linear meters × 2 sides = 8.8 linear meters

• Two horizontal crossbars: 2 × (0.9 + 0.12 × 2) = 2 × 1.14 = 2.28 linear meters

• Total: 8.8 + 2.28 = 11.1 linear meters

• Reserve: +1.1 linear meters

• To order: 13 linear meters

Window casing (on one side)

• Two vertical posts: 2 × 1.4 m (jamb height) = 2.8 linear meters

• Horizontal crossbar: 1.4 + 0.12 × 2 = 1.64 linear meters

• Bottom (windowsill) plank: 1.64 linear meters

• Total: 2.8 + 1.64 + 1.64 = 6.1 lm

• Reserve: +0.6 lm

• To order: 7 lm

Molding panel trim (if planned)

For 4 panels 500×800 mm on one wall:

• 4 panels × 3 lm = 12 lm

• Reserve: +1.2 lm

• To order: 14 lm

Final calculation table for a 14 m² bedroom

For ~32,000 rubles — a fully equipped bedroom with a unified wooden trim system from floor to ceiling. If all are finished with budget profiles (K-034 everywhere) — the amount is reduced to ~15,000 rub.

Important nuances for calculation

Reserve for cutting. Always add a minimum of 10%, and for non-standard rooms (slanted walls, niches, pilasters) — 15–20%.

Length of the piece. In the STAVROS catalog, the standard length of K-series trim is 2.4 m and 3.0 m. When calculating, consider that pieces shorter than the piece length result in leftovers. On straight walls 3.0 m long, a 3.0 m piece is ideal with no waste. On a 2.5 m wall from a 3.0 m piece — a 0.5 m leftover remains, which can be used for short sections.

Complex corners. Rooms with non-standard geometry (bay window, niche, arch) require additional reserve and precise measurement of each section.

Complete order — savings and unified style

Three reasons to order trim as a complete set

First reason: ornamental unity. Already discussed above: a unified K-series guarantees a unified profile 'language.' No ornamental conflict between baseboard and cornice.

Second reason: unity of wood species and tone. With a complete order, all elements are made from the same batch of material. With transparent finishes (oil, varnish) — the tone is absolutely uniform. This is impossible to ensure when purchasing from different places.

Third reason: unified delivery. One order — one delivery — logistics solved once. Saves time and delivery costs.

Complete order strategy for different budgets

Economy option (budget: −−):
One profile K-034 for everything — baseboard, cornice, architraves, panel molding. One purchase, one profile, minimalist result. Price: 230 rub./lm × total linear footage.

Basic option (budget: −):
K-034 — architraves and window baseboard. K-006 — floor baseboard. K-043 — ceiling cornice. Three profiles of different heights within one ornamental level. Universal result.

Mid-range option (budget: −−−):
K-006 — floor. K-071 — ceiling. K-016 — architraves. K-034 — panel molding. Classic 'mid-range' interior. Beautiful, consistent result.

High-end option (budget: −−−−):
K-009 or K-018 — floor. K-066 — ceiling. K-070 — architraves. K-016 — molding. Formal interior with rich wood trim. Representative housing level.

Luxury (budget: −−−−−):
K-104 — floor and ceiling. K-066 — architraves. Composite cornice. Molding panels from K-071. Palace interior level from standard millwork.

Additional wooden elements for a unified ensemble

To complement the millwork for a complete room ensemble:

Furniture Legs and Supports— over 130 models of turned, straight, conical legs in beech and oak. Sofa on oak legs + oak baseboard K-006 under the same oil finish — unified wooden ensemble for the lower zone.

Mirror frames RM-series— over 30 solid wood profiles. Mirror in an RM-series oak frame next to oak architraves K-006 — unified ornamental theme.

decorative overlays for furniture fronts— molding frames for cabinet and dresser doors. Complete the unified ensemble at the furniture level.

staircase components— treads, risers, stringers, balusters, handrails. For houses with stairs — unified wooden ensemble from the first-floor floor to the second-floor floor.

MLD elements— decorative elements for molding systems: corner blocks, rosettes, intersections.

FAQ: Answers to popular questions

What's better — wooden baseboard or MDF?

MDF baseboard is cheaper to purchase but cannot be restored: if damaged — only replacement. Solid wood baseboard can be sanded and repainted if damaged. With transparent finishes, MDF is not used at all — only wood. The service life of a wooden baseboard with proper care is 30+ years.

Can I buy wooden baseboard and architraves in one order?

Yes, and that is exactly what is recommended. In the STAVROS catalog, all K-series profiles are available for complete orders. One purchase — one delivery — one tone.

Which wooden millwork to choose for a 60 m² apartment?

Mid-range level: K-006 for floor and architraves, K-043 for ceiling cornice. Consumption: ~120–150 lm for the entire apartment (4–5 rooms + hallway). Material cost: ~60,000–80,000 rub. for basic profiles.

Is a wooden cornice the same as a ceiling baseboard?

Functionally — yes, both are installed at the wall-ceiling junction. But the term 'cornice' implies a richer profile with pronounced decoration, while 'ceiling skirting' is more neutral. In the K-series STAVROS, there is no distinction: any profile can be used both at the bottom and at the top.

Is special glue needed for installing wooden moldings?

Water-based liquid nails are the standard for wooden moldings on drywall and plaster. For wood (wooden slopes, wooden floor) — use D3 PVA wood glue. Important: no solvents, otherwise there will be a reaction with the varnish coating.

Wooden picture rail — does it need to be varnished before installation on the wall?

Yes. Paint / varnish before installation, including the ends. After installation — final coat and sealing of joints. This is the standard for any wooden molding.

How to calculate the linear footage of wooden moldings online?

Write down the perimeter of each room, the length of door and window openings, and the ceiling height. Fill out the table as in the example above. When ordering from STAVROS, the manager will help clarify the calculation and select profiles.
