Consider the look and feel
The expert: Phillip Thomas, interior designer
“Gallery walls can be both symmetrical when displaying pieces that are equally sized and asymmetrical when displaying pieces of varied sizes. What’s most important is to have a unifying element that brings everything together. This can be anything from the artist and medium to the subject matter and period.

“I find it very helpful to lay out all the pieces that I would like to incorporate in a gallery wall, either by drawing their outlines or laying them on the floor. While a layout may work in concept, it can have a very different feel in person when you see the pieces and their level of saturation and prominence among other pieces.
“Keep in mind the height at which pieces are hung, from both a safety and viewing perspective. Certain pieces are best appreciated from a certain vantage point – be it high, low, or at eye level.

“I don’t think there are any rules to where a gallery wall can or cannot go. I like to place it in spaces where people can engage with the art from both close up and far away.”
Think about the art itself

“Photography has become a major source of art for gallery walls. You might hang photographs framed in black with white mats along an entry hallway with a mirror on the opposite wall, or use contemporary LED lighting for a magical glow.

You can include abstract images or any interesting designs that catch your eye. Picture: Adairs
The background walls can be any colour – red, gold, or even black.
“Art walls don’t have to be composed of just two-dimensional art. I love to hang artefacts. For example, I hung a collection of Staffordshire dogs of all sizes on the walls of the cocktail lounge at Ireland’s Dromoland Castle. It was truly a visual feast for the guests.

“For the Broadway producer James Nederlander and his wife, Charlene, we hung a wall of framed playbill covers as a powder room gallery. It was an appropriate theme for theatre enthusiasts.
“In many cases, when the owner is a collector, there can be multiple art walls in a room.”
Be strategic
The expert: Dara Segal, founder & CEO, Simply Framed
“If your art is in differing shapes and sizes, don’t try to group similar pieces together on the wall. Keep it eclectic by mixing them.

Don’t space the items too far away or too close. Picture: Pottery Barn
“Spacing should be tight, with pieces five to 10cm apart, to make the design look cohesive. More than 15cm can feel too far apart; less than 5cm can create shadows from one frame to another. Keeping spacing tighter helps visually group all the pieces on the wall.
“For art that’s all the same shape and size, lay it out like a grid, keeping the spaces between each piece equal from side to side and top and bottom. It’s a super-structured modern look.”
“When in doubt, it’s usually easiest to put the largest piece in the centre and build outward. However, you generally want to avoid creating an effect where one big piece becomes, effectively, like the centre of a bull’s eye.”

If in doubt, build the design out from a larger central picture. Picture: Pottery Barn
If your centre piece is much larger than the others, don’t hang anything above or below it, and instead stack two pieces alongside to balance the weight of your central frame.
“Include different types of artwork, hang a textile, or small object to add different layers to the gallery wall.”
