That is it - but it's easier if you have a reference pinhole of known size to swap and compare.

I got it now guessing pinhole diameter with enlarger. Enlarge a 35mm or 6X6 negative , measure the enlargement ratio and than put your pinholes to the film gate and enlarge and measure the diameter of light of the pinhole and divide to the enlargement ratio. This method fits to my condition and great idea. Thanks.

Correct.
It is a slight bit easier if you use something smaller as your reference, and use much more enlargement, but a 35mm negative enlarged a lot will do in a pinch.
