What this tool answers
You need a first-pass replacement blade length for a two-wheel woodworking bandsaw. The calculator estimates loop length from equal-wheel diameter and center distance, then names a stock VEVOR US length within one inch — or returns NO_MATCH.
The πD + 2C formula
With equal wheels, each wheel contributes half a circumference, so together they contribute one full πD, and the two straight spans contribute 2C. Unequal wheels need a more complete open-belt formula; this site’s screen assumes equal wheels.
Measure at mid-tension
Set the upper-wheel tensioner near the middle of its travel before measuring C. Measuring fully raised or fully lowered can push the calculated length outside the saw’s usable adjustment.
Stock ladder on this site
Published VEVOR US woodworking stock lengths used here: 60 in, 72 in, 109.45 in, and 150 in. Matching tolerance is ±1 in to the nearest class.
When the answer is NO_MATCH
If calculated length is more than one inch from every stock class, do not force a distant blade. Re-measure, order a custom-welded length, or consult the saw manufacturer’s specified blade length.
