Work out pattern scaling instantly with clear inputs, formula shown and shareable results.
Uniform scaling multiplies every pattern dimension by the ratio of your measurement to the pattern's, which is also the photocopier percentage to use. Uniform scaling changes length as well as width, so it works for small adjustments but proper grading moves each seam by its own increment.
Scale factor
factor = your measurement / pattern measurement
Scaled dimension
new dimension = pattern dimension x factor
factor = your measurement / pattern measurement. Uniform scaling multiplies every pattern dimension by the ratio of your measurement to the pattern's, which is also the photocopier percentage to use.
Uniform scaling changes length as well as width, so it works for small adjustments but proper grading moves each seam by its own increment.
Enter pattern's body measurement, your body measurement, pattern piece dimension to scale. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
