4-6 photos are recommended for a dating profile. Yes, some apps require just one photo or allow up to 9-23 photos but that doesnt mean you should use the bar minimum or maximum. You will be judged by your worst photos so dont use bad ones.

How important are photos on dating apps?

They are crucial. Great photos can make you more interesting, make it easier to message you and make you more attractive with the right lighting, confidence, style and body language. Similarly, bad dating photos can make attractive people less desirable and make them look cringy if done poorly.
