When you’re building or renovating, choosing colours, finishes, and fittings is often the fun part. But when it comes time to choose skirting boards and architraves, many homeowners are unsure where to start. What size should they be? How do you know they’ll suit your space? The good news is: it’s not as difficult as it seems. With the right guidance – and by considering your ceiling height, home style, and lifestyle needs – you can confidently select mouldings that elevate your interior design and bring your home together beautifully.

Why Skirting and Architrave Sizes Matter

Mouldings like skirting boards and architraves are more than decorative trims. They help define the style and proportions of your home. The right size will feel balanced and intentional, while the wrong size can throw off the look of an entire room.

One of the most important factors to consider is your ceiling height.

Use Ceiling Height as a Guide

Ceiling height sets the tone for your skirting and architrave proportions. Here’s a general guide Intrim recommends:

Ceiling Height Skirting Height Architrave Width

2400-2500mm 135mm 90mm
2501-2700mm 185mm 90mm
2701-3000mm 230mm 115mm
>3001mm 285mm 115mm

These proportions help maintain balance and scale, ensuring your mouldings enhance rather than overpower your space. We recommend discussing these options with your builder, architect, or designer early in the planning process, so the right sizes are incorporated from the beginning.

Consider Practicality

If your home is busy with kids, pets, or frequent foot traffic, taller skirting boards can offer better wall protection—especially if you’re using wallpaper or dark colours where marks show more easily.

At Intrim, we consider skirtings 185mm and above as “larger,” and these suit most modern homes. If you’re working with smaller rooms or prefer a more open feel, consider a profile that has more negative space—such as a detailed top and flatter lower section—so the skirting doesn’t visually crowd the space.

Match the Style of Your Home

Your home’s design style should also guide your moulding choice:

Classic or Period Homes (e.g. Georgian or Victorian): These homes will usually feature high ceilings and traditionally use higher skirting boards – often 185mm or more to signal prestige and grandeur.
Modern Homes: For a more minimal look, keep skirtings to around 135mm high. But don’t feel limited to plain profiles—many modern mouldings feature soft curves and subtle detail that can still suit a streamlined aesthetic.

Should Skirting and Architraves Match?

While many people choose matching profiles for both, this isn’t a rule. Using different profiles for skirting and architraves can create a custom, designer look. Intrim offers a wide range of profiles and can recommend coordinated combinations to help you achieve your desired style.

Don’t Forget About Colour

Most homeowners choose to paint skirtings and architraves white or in neutral tones. This helps create a clean, timeless look and makes rooms feel more spacious.

But if you’re after something bold and unique, painted mouldings in darker or contrasting colours can add personality and draw attention to architectural detail. For example:

Colour-blocking below a chair rail can elongate a wall and create the illusion of higher ceilings.
Painting walls, skirtings, and architraves in one colour can help the eye move across the space seamlessly—ideal for showcasing artwork or a hero piece of furniture.

Get Started with Confidence

Choosing the right size and style of mouldings doesn’t have to be overwhelming. With a little planning—and by keeping ceiling height and home style in mind—you can make confident, informed choices that transform your space.
