How to take posture photos you can compare over time

Posture photos only help if they're taken the same way every time. Fix the distance, the camera height, the light and the way you stand, and you'll be able to compare them month to month. Photos can't measure a curve, though: only an X-ray can do that.

Set up once

What to wear and how to stand

Which photos to take

Take one each from the back, the front and both sides. If you like, add one from behind while you bend forward. Use the self-timer or ask a helper, take two or three of each, and keep the clearest.

Comparing them

Put photos from different months side by side at the same size, lined up by your feet. Look for trends over several months rather than changes from day to day: small differences between photos are often down to stance, breathing or the camera. If something seems to be changing, show your doctor, who can decide whether you need an X-ray.

Keep them private

Store posture photos somewhere only you can open, and think twice before uploading them to apps or services you don't trust. Zixu's photo comparison works the same way as this guide: same angle, same set-up, side by side.
