Dear Vit,
Length is automatically selected when you choose a line tool. pressing 'M' seems to be equivalent to the control-m or command-m for the Measure command. (That is a new behavior to me. but I never had any reason to stray from the old command-m.) You could also threshold and select your particles with the magic wand tool or use Analyze Particles, which might be more efficient than drawing lines, provide Feret and MinFeret, but no straight line length.
