Question 1

How do I enter fractional measurements?

Accepted Answer

Type values like "12 1/2" or "2 1/4" directly into any dimension field. Kerf parses mixed numbers, decimals, and fractions. In inches mode you can also use the compound feet-and-inches format.

Question 2

Why doesn't my 3/4" cut fit on my 1/2" sheet?

Accepted Answer

Kerf tracks material thickness and only matches cuts to compatible stock. A 3/4" piece cannot be made from 1/2" stock. Check the Thickness field on each cut piece and each stock sheet to make sure they match.

Question 3

Can I use metric?

Accepted Answer

Yes. Open a project's Settings tab and choose Millimeters or Centimeters. Kerf stores all values in inches internally, but display and input adapt to whichever unit you pick.

Question 4

Can I export my layout?

Accepted Answer

Yes. From the Results screen, tap the ⋯ menu and choose Share PDF or Share PNG. The export uses the native iOS share sheet, so you can AirDrop to another device, save to Files, or send it via any installed app.

Question 5

Does Kerf handle grain direction?

Accepted Answer

Yes. Each stock sheet has a grain direction (along the long or short edge), and each cut has a "Grain matters" toggle. When grain is locked, the solver will not rotate that piece during packing.

Question 6

Where is my data stored?

Accepted Answer

Entirely on your device using SwiftData. Kerf has no server and never sends your project data anywhere. See our Privacy Policy for details.

Question 7

How do I report a bug or request a feature?

Accepted Answer

Email support@thekerfapp.com with a description of what you ran into. For bugs, please include what you were doing when the issue occurred — the more specific, the faster the fix.
