Art.com is also a good place to shop.

You could check Etsy for triptychs, and Eleanos Gallery has some nice sets of 3 in larger sizes, especially if you like abstract or textured art.

Not a fan of triptych artwork. Somehow it seems rather commercial. Would you be open to seperate pieces that coordinate well together?

Show us your space IMO that is the only way to get help.I rarely like any triptych type are and without seeing your space it is impossible to know if that is what you need. In the pic you show I would have done one very large fab piece of art not bought off the internet at all and a much better chandelier.

Size won’t be hard to find…but content/style/frame/price are personal and searching is your best bet (Etsy is a good place to start or Wayfair if cost is a big factor).

I searched Pinterest for ”Set of 3 paintings 30x40“ and immediately found this site. Research/comparing is a good place to start. Always check the return policy.
