Icon Calculator for Mac

From Narattaphol Charoenphandhu:

5{tor is a little application developed for predicting output size of an icon set generated by Iconizer Pro, and suggesting the right image size. (If size of Iconizer Pros source image is not x times of 32, iconizing engine will add a white border to fill the gap.) It contains low-level codes which take little system resources and CPU times. So you can use it with CPU-consuming graphic editors. In addition, use of Icon Calculator is a fast way to obtain images' sizes from files and clipboard. This is suitable for software developers or graphic designers who want to allocate a space on the window or canvas for an image.
