When choosing a colour palette, try to either have the art match the colour palette of the space, or use a totally opposite colour scheme to make it pop. When choosing colour, consider if you would like your art print to draw the eye or blend in harmoniously. Trending colour palettes are neutrals, greys and pastels, but feel free to experiment and have fun with colour!
People tend to choose art that is too small for a wall. If you’re just hanging one or two pieces say over a couch, make sure they’re large enough to fill the space, 24”x36” and up. For a gallery wall or a smaller space, I recommend using 8”x10” to around 20”x28”, with maybe one larger piece at 24"x36". Remember when you’re hanging a large piece of framed artwork on a plaster wall to either hang from a wall stud or use wall plugs so the weight can be supported properly.
Similar to colour, consider if you would like the frame to blend into the artwork, or be a bold accent. I usually choose simple wood frames for my pieces, but vintage frames with scrollwork are making a big comeback with the rise of interior design styles like dark academia. For a clean minimalist look, go for a simple black wood frame, and for a more boho or Scandinavian look, use a maple or grey frame.
Artwork is very subjective, everyone likes different styles. I can however recommend if your room is modern to use styles like abstracts or line art to compliment your room. If your space is traditional, you may prefer landscapes or photography. Take some time to browse Pinterest with relevant keywords to find art styles you may enjoy, such as searching “modern bedroom” or “Scandinavian living room”.
