Material Quantity Calculator

Any craft material, from your own coverage rate: how much the project uses, and how many packs to buy.

Project size units

Square metres, linear metres, square centimetres, pieces: whatever the rate below is measured against.

Your consumption rate per unit

Material per unit of project size. Measure it on a test piece or take it from the supplier data.

Waste and overlap allowance %

Five percent for a predictable job, ten to fifteen for a first attempt.

Material in one pack units

The bag, tin, roll or box size you are buying. This is what turns a quantity into an order.

Price per pack

Optional. Used for the cost figures.

How many projects

Material already in stock units

Anything left from a previous project. It is deducted from the order, not from the requirement.
