120mm Skirting Boards

At 120mm you're choosing one of the most popular skirting board heights in UK homes, a practical mid-height that suits standard 2.4m ceilings and looks right in almost any room. It's a clear step up from a 95mm board, giving walls a more substantial, finished look without dominating a smaller space the way a taller board can. In the joinery trade it is often sold as a 5 inch skirting board, although the true height is 120mm (about 4¾ inches).

Every one of our MDF skirting profiles is made at 120mm, from clean contemporary designs like Bullnose, Square and Chamfer to traditional Ogee and Torus. Choose unprimed, primed or undercoated for painting, or a painted Matt Grey or Satin Black finish, in your preferred thickness and length. Prefer real timber? Our Pine range runs to a closely matched 119mm.

120mm Skirting Board FAQs

Is 120mm a standard skirting board height?

Yes. 120mm is one of our standard MDF skirting board heights, available across every skirting profile we make, from contemporary Bullnose, Square and Chamfer through to traditional Ogee and Torus. Our standard heights run from 70mm up to 400mm, and 120mm is one of the most popular mid-heights for modern UK homes.

How many mm is a 5 inch skirting board?

In UK joinery, 5 inch is a nominal trade name, not the exact measurement. The board sold as 5 inch is finished at 120mm, about 4¾ inches (4.72 inches), just under a true 5 inches (127mm). So if you have searched for a 5 inch skirting board, 120mm is the size you want. For a precise imperial size, or a height we don't list as standard, we can cut bespoke sizes to order.

What rooms suit a 120mm skirting board?

120mm suits most UK rooms, particularly modern homes with standard 2.4m ceilings, where it sits in proportion without overwhelming. It's a step up from a 95mm board, covering more of the wall and giving a more substantial finish, while staying neat in hallways, bedrooms and living rooms alike. For rooms with higher ceilings or a period feel, a taller board often looks better.

Should I choose 120mm or a taller skirting board?

It comes down to ceiling height and the look you're after. 120mm is the safe, popular choice for standard ceilings and most modern interiors. If you have higher ceilings, larger rooms or a period property, a taller board can look more in proportion. Browse our 145mm and 170mm skirting boards or the full tall skirting board range.

Do you make a 125mm skirting board?

Our standard heights either side of 125mm are 120mm and 145mm. If you need exactly 125mm, for example to match existing skirting, we can cut bespoke sizes to order.

What thickness, lengths and finishes are available?

Every 120mm board comes in 25mm thickness, and most profiles also come in 18mm and 15mm. The thickness options on each product show what that profile offers. Lengths are 3050mm and 4200mm. Choose unprimed, primed or undercoated for painting, or a painted Matt Grey or Satin Black finish, with an optional rebate for pipes and cables. Prefer real timber? Our Pine range includes a closely matched 119mm. Every board is made to order in our Birmingham factory from moisture-resistant MDF.
