Skirting Board Calculator: Measure Once, Order Right, and Never Make Three Trips to the Merchant
Skirting board is one of those finishing touches that can make a room look properly done — or, if you get it wrong, leave you short on site with a half-finished wall and a long drive back to the merchant. Working out how much you need, what it'll cost, and how many lengths to order doesn't have to be a headache. This guide walks you through exactly how to calculate skirting board in both metric and imperial, estimate your costs, and use a skirting board calculator to take the legwork out of it.
Why Getting Your Skirting Board Calculation Right Actually Matters
Think of ordering skirting board without measuring properly like doing the weekly shop with no list and a blindfold — you'll either come home with too much of the wrong stuff, or not enough of what you actually need. Getting your numbers right means:
- Saving money by only buying what you need
- Avoiding wastage and leftover materials
- Ensuring a professional, seamless finish
- Making ordering and fitting far simpler
The Simple Way to Measure for Skirting Board
Before you spend a penny, you need the total length of skirting required. Here's the process — it's quicker than it sounds:
- Measure each wall: Run a tape along every wall where skirting will go. Don't forget alcoves, bay windows, or any awkward nooks — they all add up.
- Add them up: Write down every measurement, then tot them together for the total perimeter.
- Subtract for doors: Measure the width of any doors (and floor-level built-in cupboards) and knock those off your total — no skirting needed there.
- Add a little extra: Build in an extra 5–10% for cuts, corners, and the odd mistake. Think of it as the spare teabags you keep so you're never caught short.
Worked Example: Metric & Imperial
Let's run through a typical room so you can see exactly how it plays out:
- Wall 1: 4.2m (13ft 9in)
- Wall 2: 3.6m (11ft 10in)
- Wall 3: 4.2m (13ft 9in)
- Wall 4: 3.6m (11ft 10in)
Total perimeter = 4.2 + 3.6 + 4.2 + 3.6 = 15.6m (51ft 5in)
Subtract a standard door (0.76m / 2ft 6in):
15.6m - 0.76m = 14.84m (51ft 5in - 2ft 6in = 48ft 11in)
Add 10% for cuts: 14.84m × 1.10 = 16.32m (rounded: 16.5m or about 54ft)
So you'd be ordering around 16.5m (54ft) of skirting board. Simple as that.
How Many Lengths Will You Need?
Here's where people often get caught out. Skirting boards are sold in set lengths — commonly 2.4m (8ft), 3m, 3.6m, or 4.2m in the UK. Divide your total by the length available and always round up. Never round down. Ever.
| Skirting Board Length | Number Needed (16.5m total) |
|---|---|
| 2.4m | 7 |
| 3.0m | 6 |
| 3.6m | 5 |
| 4.2m | 4 |
To skip the maths entirely, our skirting board calculator tool works out exactly how many lengths you need based on your specific measurements.
Estimating the Cost of Skirting Board
Prices shift quite a bit depending on material, profile, and finish. Skirting is usually priced per metre or per length — here's a quick breakdown of what you're looking at:
- MDF (primed): Usually the most affordable — solid choice for painted rooms
- Softwood: Mid-range, takes paint or stain well
- Hardwood (oak, walnut): Premium option, and the price reflects it
Example calculation:
If MDF skirting costs £4 per metre and you need 16.5m:
16.5m × £4 = £66
Don't forget to factor in delivery, paint, and any fitting costs — they have a habit of sneaking up on you.
Painting & Finishing
If your skirting arrives unfinished, you'll need to think about paint coverage too. Most paints cover 10–12m² per litre. For skirting, the surface area calculation is straightforward:
- Height: 120mm (0.12m)
- Length: 16.5m
- Area: 0.12 × 16.5 = 1.98m²
One litre will comfortably cover this with two coats — you won't need a second tin.
Fitting Costs
Labour rates vary by region and how complex the job is. In the UK, professional fitting typically runs from £6–£12 per metre. Intricate profiles or awkward rooms can push that figure up, so always get a few quotes before you commit.
Using a Skirting Board Calculator
If mental arithmetic isn't your idea of a good time on a Monday morning, a skirting board calculator does the heavy lifting for you. Punch in your wall measurements, and it spits out exactly how much material you need — no rounding errors, no forgotten alcoves, no second trip to the merchant. It's like having a quantity surveyor in your pocket, but free and without the invoice.
Questions People Are Actually Asking
How much skirting board do I need?
Measure every wall that'll have skirting, subtract openings like doors, then add 5–10% for waste and cuts. If you'd rather not do it by hand, a skirting board calculator gives you the answer in seconds.
How much does skirting board cost?
It depends on material and profile. In the UK, MDF skirting typically runs £3–£5 per metre, softwoods sit at £5–£10, and hardwoods can reach £10–£25 per metre. Always add fitting and finishing costs to your budget — they're not optional extras.
How much is skirting board per metre?
Prices range from around £3 per metre for basic MDF up to £25 per metre for premium hardwoods. Check with local suppliers for exact figures in your area — prices can shift depending on where you are and who you're buying from.
How much for skirting board fitting?
Professional installation usually costs £6–£12 per metre. Complex rooms or detailed profiles can push the price higher. Always ask for a written quote before anyone picks up a nail gun.
How much skirting board paint do I need?
One litre of paint covers around 10–12m². For a standard room with about 16m of skirting at 120mm high, you'll need less than a litre for two coats — so don't go buying a five-litre trade pot for this one.
How many skirting boards do I need?
Divide your total required length by the board length sold (e.g., 3m or 4.2m per board) and round up. A calculator can work this out for you automatically — no long division required.
How much to skirting board a room?
Add together the cost of the skirting board, paint, and fitting. For a 16m room with MDF skirting and basic fitting, expect a total somewhere in the range of £120–£250 depending on finishes and labour rates in your area.
