Buy the right amount of lumber and get a cut plan based on your parts list.

Save a trip to the lumber store by planning your project with precision. KerfMaker makes sure you get just enough wood for your woodworking project.

Designed by a woodworker, KerfMaker has the tools you need to help keep your lumber costs low and your project together. With KerfMaker's project planner, you'll assemble a precise list of boards needed to get your project done – and make sure you only need to make one trip to the lumber yard or hardware store.

“...easy to learn, very useful. Sorts my parts quickly. Worth the purchase!”

Pick your boards, plan your cuts and put it all in one place.

Use the parts list to keep track of everything you need to assemble.

Organize your projects with photos, and share existing projects with other woodworkers.

What’s New

Version 1.2.7

Fixes were made to ensure that image capture and certain input dialogs work properly on iPad. Analytics has been totally removed so KerfMaker does not collect or share even anonymized data. This version runs on Macs with Apple silicon, though its user interface design needs improvement there.

Nice app

Just bought it. Has nice features like adding new materials types and prices to calculate costs. Can’t tell if the measurements in the app use nominal or actual sizes and whether I need to adjust for that.

Developer Response ,

The measurements are actual sizes and KerfMaker adds a kerf width around each part. If you still have questions about this, please contact me through the form at and I will do my best to answer. Thanks!

Useful, but could use some updates

First, this app does exactly what it says - it helps you plan out your next build. That said, I do have a few complaints. Or, rather, suggestions for improvement. First, it’s not iPad optimized; I have a phone sized display in the center screen that’s difficult to use. Second, the sizing is done by a scrolling wheel for inches and fractions; putting in a piece that’s 84” long means scrolling all the way to 84. A simple keypad would alleviate this. Third, there’s no option for plywood as a building material, only a generic “wood” option.

In light of these shortcomings, I can only give it 3 stars for the moment. If these were addressed, I wouldn’t hesitate to give 5 stars.

Thank you for trying KerfMaker and for your feedback! If you would contact me through the feedback form on I would like to ask you a little more about your suggestions.

Very useful

Does exactly what it says. I use it all the time, for remembering dimensions of all sorts of sites and workpieces around the house.

I wish it had an option to sync by iCloud instead of Dropbox. I wish it were quieter about syncing unless it's taking a while. I'm still giving it five stars.

AR measurements would take it to a whole other level.

Thanks for the feedback! I've been thinking about what's in the next version and it's super helpful to know what you think would be useful.
