Cedar logs can grow round, oval, squarish, rectanglish and trianglish. I have gotten perfect 6" square cants that were measured at 7". Actual measurement was right at 7 3/4" and the log was very squarish. So that is paid for 14, sawed 24.

The best way is to do them as a group of logs since there is so much a wide variation in log shape and ingrown bark.

Measure 20 or 30 logs, saw them, measure the good lumber and the low grade lumber. Now you will have an average yield. It is almost impossible to get an accurate estimate of what any individual log will saw out.

Remember a 7" log can have almost 14 per cent difference based on diameter measure alone. It may measure exactly 7" all the way to 7 15/16" and be called a 7" log. Cedar log measure calls a 7" log at 14 feet and an 8" log at 19. (Some cedar scales call a 7" at 15 feet). So that is a 36 per cent change in footage using the scale.

Have fun sawing cedar.
