What aperture for street photography?
The aperture for street photography is f/5.6 and f/8. That's the short answer, but this does not take into account what light situation you are in and what you want to do. F/5.6 and F/8 are loved by street photographers because of the large depth of field, and there needs to be enough light too.
A quick primer on aperture
Aperture refers to the opening of the lens. The larger the opening the smaller the number, so an aperture of 1.8 is wide open while f22 is pretty darn closed:
When the aperture is OPEN more (like f/1.8) the depth of field is very thin, great for making backgrounds blurry. But when the aperture is CLOSED (like f/22) the depth of field is large.

A more sober answer
So while f/5.6 and f/8 are great apertures…what if you want your background blurry and there is not enough light? Then a higher aperture will be in order. F/5.6 and f/8 are the apertures that strike a balance between having a lot of depth of field and still have enough light come in so that the shutter speed is fast enough. Because things happen fast in street photography and you don't want a slow shutter peed to ruin your shots.
