If I have a project that needs “X” amount of board feet of lumber, how much extra should I estimate and purchase to include waste, cutoffs, screw-ups, and other things?

An extra 10%, 20%, 30%?

I’m sure it varies to some extent for each person, but considering I’m still relatively a beginner, what would you recommend?

- Thanks, Kevin

I do 20%. It gives you some choices and some scrap. Better than running out.

I agree with Giz. The other consideration is in price break. If you get a price break with a certain amount, i.e. 100 bf, you may just want to buy the number of bf to get the price break. This gives you extra lumber for the next project.

Also depends on the type of wood. I order clear Alder I get 3 inch wide by 6 feet stock…I order Oak I get 10 inch wide by 12 feet.

Sometimes I’ve bought No. 2 oak boards for a very good price. I bought plenty because if you eliminate the knots,

it takes more, But lumber that has knots in it tends to have more figure in the grain.
