Measure_Rois
The macro calls the Measure Roi plugin for each selected ROI in the roi-manager or for all the ROIs in the roi-manager, if none are selected. It adds the length and width of each roi to the line of the roi in the Results-table.
Install the Measure Roi plugin if you do not already have it. Download the macro measure_rois.ijm, save it into the plugins-folder of your ImageJ installation and restart ImageJ.
You can run the macro from the Plugins-menu or using the ImageJ search-bar.
