Estimate your waste volume and find the right skip size for the job.
Recommendation allows ~10% headroom because skips must be filled level, not heaped. Heavy rubble and soil are often restricted to smaller skips (2, 6 yard) on weight grounds, check with your supplier.

How to use the skip size calculator
Tell the calculator roughly how much waste you have and it suggests the right skip size, from a mini skip up to a roll on roll off, so you neither overpay for space you will not use nor run out mid job. It is a quick sense check before you book a delivery.
Frequently asked questions
What sizes of skip are available?
Common sizes are the mini (2, 3 cubic yards), midi (4, 5 yards), builder's (6, 8 yards) and large maxi or roll on roll off skips (10, 40 yards) for bulky or high volume waste.
Which skip size do I need?
Estimate your waste in bin bags or cubic yards: a mini suits a small clear out, a builder's skip suits a typical renovation, and roll on roll off skips suit major projects. The calculator matches your volume to a size.
Can I overfill a skip?
No, skips must be filled level with the top for safe, legal transport. If you are close to the limit, size up rather than overfill.
