Pupil Size Charts
DiagramsA pupil size chart gives a quick visual gauge for measuring pupil diameter in millimeters, a small tool that comes up often in nursing, optometry, and first-aid training. This collection of 25 charts helps students and clinicians estimate and document pupil size consistently.
Each chart is a print-ready PDF, so you can print one at exact size and keep it on a badge card, in a binder, or by a workstation. For accurate millimeter markings, print at 100% with scaling off. These are reference and study aids rather than diagnostic tools, so rely on proper clinical judgment for patient assessment. Choose the chart that suits your use and print a copy to keep handy.
