Skirting Board Calculator: Never End Up a Metre Short Again (or Buy Enough for Next Door)

Ever started a room, only to realise you’re one length of skirting board (baseboard) short, and the merchant’s already shut? Or gone the other way and ordered enough timber to redo the neighbour’s house too? If this sounds familiar, you’re not alone. Measuring skirting board without a plan is like trying to tile a bathroom by eye: what could possibly go wrong? (Hint: plenty.)

In this guide, you’ll learn to calculate exactly how much skirting board (or baseboard, for our friends across the pond) you need, how to factor in corners and wastage, what it’ll cost, and how to plan your shopping list so you only make one trip. Bonus: we’ll show you how to use a calculator tool that does the sums in seconds.

The Skirting Board Take-Off: Why Getting It Right Matters

Here’s the bit most people get wrong: they measure one wall, add it up in their head, and hope for the best. That’s like doing your weekly shop with no list and a blindfold. You’ll either come back with three bags of flour and no milk, or forget half the essentials entirely.

Skirting boards aren’t just about looks—they cover the messy join between wall and floor, protect your plasterwork (drywall), and, if you get the wrong length, they’ll be the first thing to shout ‘DIY disaster’ to every visitor. So, let’s get it right the first time.

Step-by-Step: How to Measure for Skirting Boards (Baseboards)

1. Measure Every Wall (Don’t Guess!)

• Grab your tape measure and go wall by wall, noting the length of each in metres (and feet).
• For alcoves, bay windows, or chimney breasts, measure every return—you’ll want the board to wrap all the way round.

2. Add Up Your Total Perimeter

• Add all your wall measurements together for the full room perimeter.
• Example: 3m + 4m + 3m + 4m = 14m (that’s a 3m x 4m room, or about 10ft x 13ft, so 46ft total perimeter).

3. Subtract Gaps

• Doors, fitted cupboards, fireplaces, and anything else you won’t skirt—knock those lengths off your total.
• Example: If your door is 0.8m (2ft 7in), subtract that from your 14m (46ft): 14m - 0.8m = 13.2m (46ft - 2.7ft = 43.3ft).

4. Add a Wastage Allowance (Trust Me on This)

• Offcuts, miscuts, and the odd wall that’s not quite square—wastage is the spare teabags you keep so you’re never caught short.
• Add 10% to your total. It’s better to have a bit left over than come up short by 30cm (1ft).

Worked Example: Let’s Do the Maths (Metric & Imperial)

Let’s say you’re fitting skirting board in a 3m x 4m (10ft x 13ft) room, with one standard door (0.8m/2.7ft) and a built-in cupboard (1m/3.3ft).

1. Measure all walls: 3m + 4m + 3m + 4m = 14m (46ft)
2. Subtract gaps: 14m - 0.8m - 1m = 12.2m (46ft - 2.7ft - 3.3ft = 40ft)
3. Add 10% wastage: 12.2m x 1.1 = 13.42m (40ft x 1.1 = 44ft)

So, you’ll need about 13.5m (44ft) of skirting board.

Most skirting comes in 2.4m (8ft) or 3m (10ft) lengths. Divide your total by your chosen length and always round up:

• 13.5m ÷ 3m = 4.5 → buy 5 boards (44ft ÷ 10ft = 4.4 → buy 5 boards)

Nobody has ever finished a job saying they wish they’d bought less.

Buying Skirting Boards: What to Watch Out For

Bet the merchant never told you this... Not all skirting (baseboard) is created equal. Here’s what you need to know before handing over your card:

• Lengths vary: Some boards are 2.4m (8ft), others 3m (10ft), and in North America, you’ll see 8ft, 12ft, or even 16ft lengths. Don’t mix and match unless you want a jigsaw puzzle for a floor.
• Profile matters: From classic ogee to square and modern, pick a style that suits your house (or your client’s taste).
• Material choice: MDF (medium-density fibreboard) is smooth and cheap; softwood is easy to work; hardwood is pricier but hard-wearing. In the US, you’ll see pine, poplar, or composite too.

How Much Will It Cost?

How long’s a piece of string? But seriously, here’s a ballpark:

Material	Cost per metre (per foot)
MDF	£3–£5 (US$4–$7) / m (£1–£1.50 (US$1–$2) / ft)
Softwood	£5–£8 (US$7–$11) / m (£1.50–£2.50 (US$2–$3.50) / ft)
Hardwood	£10–£20 (US$14–$28) / m (£3–£6 (US$4–$8) / ft)

Fitting costs vary wildy depending on region and job size, but expect to pay a pro £7–£15 (US$10–$20) per metre (£2–£5 (US$3–$7) per foot) fitted, including labour and fixings. DIY? Just the material cost, and a few hours of your weekend.

Painting and Finishing: Don’t Forget the Extras

Painting skirting (baseboard) is the icing on the cake. Most people forget to allow for paint—then realise halfway through they’re scraping the bottom of the tin.

• One litre (US quart) of paint covers roughly 12–14m² (130–150 sq ft).
• For skirting, you’re only painting the face and maybe the top edge, not the whole wall. Measure the height and length to get the area, e.g. 13.5m (44ft) x 120mm (5in) high = 1.62m² (17.6 sq ft).

So, one tin goes a long way—unless you’re painting skirting in every room in the house.

Quick Recap: Skirting Board Take-Off in 4 Steps

1. Measure every wall (in both units!)
2. Subtract doors, cupboards, fireplaces
3. Add 10% for wastage
4. Divide by board length, round up to whole boards

Questions people are actually asking

How much skirting board do I need?

Measure all the walls you want to skirt, subtract the width of doors and fixed units, then add 10% for wastage. Divide by the length of skirting boards you’ll buy (e.g. 3m/10ft) and round up to the nearest whole board. Or use a cut-to-fit skirting board calculator to do it for you.

How much does skirting board cost?

It depends on material and profile. Budget for £3–£20 (US$4–$28) per metre (£1–£6 (US$1–$8) per foot). Add extra if you’re paying for fitting or want a premium hardwood.

How much is skirting board per metre?

Prices vary: MDF is cheapest (£3–£5 (US$4–$7) per metre/yard), softwood is mid-range, and hardwood can be £10–£20 (US$14–$28) per metre.

How much for skirting board fitting?

A pro will typically charge £7–£15 (US$10–$20) per metre (£2–£5 (US$3–$7) per foot) fitted, but this can be higher for complex jobs or awkward rooms.

How much skirting board paint do I need?

One litre (US quart) of paint covers about 12–14m² (130–150 sq ft). For a single room, you’ll usually need less than one tin. Calculate the area by multiplying the length of skirting by its height, then check your paint’s coverage rate.

How many skirting boards do I need?

Take your total required length (including wastage), then divide by the length of a single board (e.g. 3m/10ft). Always round up—you can cut down, but you can’t stretch timber.

How much to skirting board a room?

Add up the cost of materials and, if using a tradesperson, labour. For a small room, expect £60–£200 (US$80–$250) all-in, depending on finish and complexity.

Conclusion: Measure Once, Order Once, Fit Like a Pro

Don’t let your skirting project turn into the DIY equivalent of a bad haircut—measure up properly, allow for wastage, and buy what you need.
