How to choose the right skip size.
Skips are measured in cubic yards, a unit nobody has used for anything else since about 1974. Here’s how to translate your pile of waste into the right skip — first time, without paying for air or ordering twice.

Every week someone rings the office, describes a job, and asks what size skip they need. It’s the most common question we get, and the honest answer is that most people’s first guess is one size too small. Waste expands the moment you start pulling it out of a house — a fitted wardrobe that lived quietly against a wall becomes an aggressive pile of chipboard the moment it’s in bits on the lawn.
Order too small and you’re paying for a second skip and waiting for a second delivery. Order too big and you’ve paid to move fresh air around Leeds. The trick is a bit of arithmetic, a couple of rules, and a healthy suspicion of your own optimism. All three below.
Start with bin bags.
Nobody can picture a cubic yard. Everybody can picture a bin bag. The conversion is roughly ten full bags per yard, and it holds up well enough to size a skip by.
Run the numbers and the range looks like this: a 2-yard mini holds about 20 bags (from £130 inc. VAT), a 4-yard midi about 40 (from £170), an 8-yard builder’s skip about 80 (from £270), and the 16-yard maxi around 160 bags (from £510). Full dimensions and live prices for the whole range are on the skip sizes page.
The method: look at your pile — or the rooms it’s still hiding in — and count it in bags. Then add a third, because in nine years of deliveries we have never once heard “we had loads of room left, actually.” Bulky items make the maths lie in one direction only: a sofa is technically about a yard of material, but it takes up two yards of skip because it refuses to squash. Furniture, wardrobes and anything with legs — count them generously, or better still, break them down before loading.
Or just match the job.
If counting bags feels like homework, here's the same answer arrived at the practical way: what we actually deliver for each kind of job, week in, week out.
Bathroom rip-out
2 yard
A suite, the tiles and the boxing-in. It looks like more than two yards when it's on the floor; it isn't.
Garden clearance
4 yard
Green waste refuses to compress and turf is heavier than it looks. Go a size up from your instinct.
Kitchen refit
4 yard
Units, worktops and flooring. The old fridge stays out — fridges can't go in any skip.
Whole-house clear-out
8 yard
Furniture eats volume at a frightening rate. An 8-yarder swallows a three-bed house's worth.
Extension or landscaping
8 yard
The biggest skip that legally takes soil, rubble and hardcore. Fill it level and it's the maximum single load of muck.
Shop or office strip-out
16 yard
Racking, partitions, packaging — bulky and light. Exactly what the maxi is built for.
Two jobs that don’t appear above: anything producing serious tonnage of muck — footings, a driveway dig-out — is often better served by a grab lorry than a skip, and a site producing waste continuously wants a roll-on-roll-off container on exchange. Both live on the services page.
Level with the rim is full.
Whatever size you pick, there's one definition of 'full' that matters: the driver's.
A skip has to travel with a level load — nothing mounded above the sides, nothing balanced on top, no doors or fence panels standing proud like sails. Anything higher than the rim can shed onto the road, which is why an overfilled skip can’t legally be carried. The driver isn’t being awkward when he asks you to level it off; he’s the one whose licence rides on it.
In practice this means the last week of a project is when size mistakes surface. People load the easy bulky stuff first, run out of room, and start building upwards. If you can see the load creeping above the sides with waste still to go, ring us beforecollection day — extending the hire or swapping to a bigger plan costs far less than a lorry arriving for a skip it can’t take. Load flat things first, break furniture down, and pack the voids: a tidily loaded skip genuinely holds a third more than a thrown-in one.
Heavy waste changes the answer.
Skips are sized by volume, but lorries are limited by weight — and soil and rubble hit the weight limit long before they hit the rim.
This is why the size question isn’t only “how much stuff?” but “what kind of stuff?”. Soil, rubble, hardcore, tiles and plaster are accepted in the 2, 4 and 8-yard skips, loaded level. The 16-yard maxi is light waste only — a maxi full of hardcore would weigh well beyond anything a skip lorry can legally lift, which is why no reputable firm anywhere will collect one.
So for a renovation producing both — say a kitchen refit with a wall coming down — the 8-yarder is usually the right call: big enough for the units and flooring, still legal for the brick. And if the job is muck from top to bottom, an 8-yard filled level with hardcore is the largest single skip-load there is; beyond that you’re into grab territory. The deeper reference version of all this, with dimensions and driveway checks, is our full skip size guide.
One big skip beats two small ones — usually.
Skip pricing doesn't scale with volume, and the arithmetic is worth thirty seconds of your time.
At our from-prices, two 4-yard skips cost £340. One 8-yarder — the same capacity — costs £270. That’s £70for the privilege of waiting in twice for deliveries and twice for collections. Doubling the size never doubles the price, so when you’re torn between two sizes, go up. The gap between sizes is always smaller than the cost of a second skip.
That said, two small skips genuinely win in three situations. First, access: if the only spot is a short drive or a permit bay where an 8-yarder won’t sit, two 4-yarders in sequence solve it. Second, heavy waste in bulk: since heavy waste stops at 8 yards, a big muck job sometimes has to move as two loads whatever the spreadsheet says. Third, phased jobs: a strip-out in March and a garden in June are two hires, not one long expensive one. Everything else — take the bigger skip.
Still torn? Ask us.
We size skips over the phone all day and we'll tell you honestly when the smaller one will do — a wrongly sized skip costs us a wasted journey too.
Every price includes VAT, delivery, collection and seven days’ hire.
