What are you building?
Useful numbers, clear assumptions, and a list you can take to the supplier.

From idea to materials
A good project starts
with a sensible plan.
No mystery prices or one-size-fits-all quantities. Use your measurements, your product sizes and your supplier’s prices.
Choose metres or feet and enter the area you actually plan to cover.
Set product sizes, waste and prices to match the materials you will buy.
Print or download quantities and assumptions before requesting a quote.
Before the first cut
A little know-how.
01 / Measure

Break awkward spaces into simple shapes and avoid double-counting.
02 / Allow
Waste, cuts and whole packs
Understand why coverage and purchased quantities are different.
