Leather Project Area and Material Cost

List the pieces of your project with their width, height and quantity. You get the total area in square millimetres and square metres. Add a price per square metre and a waste allowance of your own to see a material cost.

Net area of the pieces (m²)

0.12

120000 mm² · 2 pieces over 1 line

  • Line 1

Net cutting area only: it is not the area of hide to buy. The price and the waste allowance are yours; thread, hardware and other costs are not included.

How it works

  1. Add one line per piece size: width and height in millimetres and the quantity.
  2. Read the total area in square millimetres and square metres.
  3. Optionally enter your price per square metre and the waste allowance you choose.
  4. Copy the summary or the list as CSV.

Questions

What are the formulas?
Area in mm² = the sum of width × height × quantity over all lines. Area in m² = area in mm² ÷ 1 000 000. Cost = area in m² × price per m² × (1 + waste allowance ÷ 100).
Is this the area of hide I need to buy?
No. It is the net area of the pieces. Hides are irregular and have flaws, and the way pieces nest changes what you need. The waste allowance is your own assumption, not a yield.
Does the page know any price?
No. You enter the price. Nothing is fetched, and the page does not include thread, hardware, tools, tax or shipping.
Can I use another unit than millimetres?
The list is in millimetres. For another unit, convert the sizes first with the length converter on this site.
