Start with an anchor: your largest print (50×70 or
bigger), hung at eye level. Build outward with 2–3
30×40s and a few A4s, keeping gaps consistent —
5–8 cm reads as deliberate.
Unity comes from one repeated element: a shared colour, a shared
frame, or a shared theme. Mixing subjects works when the palette
agrees; mixing frames works when the subjects agree.
Lay the arrangement on the floor first, photograph it, and live
with the photo for a day. Then commit — and remember that
gallery walls are meant to grow. Leave room for the next print you
fall in love with.
