FRAMEMAC & LMS Strip Width Calculator

Strip Width Calculator

Works for C, U, V, Z, hat, or any straight-segment profile — build it segment by segment.

Material Settings

Material thickness (t)

Inside bend radius (R)

K-factor

Thickness, radius and K-factor feed the automatic bend deduction estimate below — used for every bend unless you override it individually. Not sure about K-factor? 0.4338 is a common starting point for air bending; use the calibration section further down to refine it against a part you've actually measured.

Profile — segments & bends

Build the profile in order, edge to edge. Start with the first flat length, then add a bend and the next flat length, and so on.

0.0mm

Flat strip width

Calibrate with a measured strip

Build the profile above for a part whose actual strip width you already know, enter that measured width below, then press Calculate. The tool works out the correction needed per bend for the current thickness and remembers it for this session — applied automatically next time this thickness comes up.
