In some cases, a structure is visible by directly looking at the microscopy slide, and if it is well-demarcated, a regular ruler can be used to measure it. Otherwise, you will generally need to make the measurement microscopically. For this purpose, you can use a calibration slide, which is basically a translucent ruler with 0.1 mm line resolution or smaller, which may cost about $15 if none of your colleagues has one to lend, or the department can't provide one for you. | In some cases, a structure is visible by directly looking at the microscopy slide, and if it is well-demarcated, a regular ruler can be used to measure it.
