You can choose option “Scale to Absolute Width and Height” if you want to be able to define both width and then heightened independently.

Other important tips.
Because the major feature of star watermark program is adding text or image watermark to photos, if you just want to resize photo files, not add a watermark to photos, please open “Edit Watermark Template” window by a double-click on one watermark template like “Demo 1”, then delete watermark text.
