Should a painting go inside an arched niche?

Why the niche should not hold the painting

In short: no, the niche keeps a standing object; the painting goes on the flat wall above the sofa, bottom edge 15 cm above a low sofa back.

An arched niche already has a shape of its own: a curve that pulls the eye toward itself. Slide a rectangular frame into it and the two geometries compete, and the arch almost always wins, drawing the eye to its own curve rather than to the subject of the painting. The niche does best with what it is built for, an object sized to it, a jug, a small vase, something whose outline benefits from the absence of square corners rather than fighting them.

It is an easy mistake to make because a niche looks like a ready-made frame. It is one, just not for a painting: for an object that does not need right angles.

The right wall: the flat panel above the sofa

The flat wall right next to the niche is the only surface in the room at the right scale for a painting this size. It is wide enough to leave air on both sides of the frame, and tall enough, under a ceiling that steps back above the sofa, that the painting never crowds the cornice.

Hanging it here instead of in the niche also solves a light problem: the niche stays in shadow for most of the day, while the wall above the sofa catches the low, raking light that crosses the room from the window in the late afternoon.

How high, with a sofa this low?

This sofa has a low back, around 70 cm. The usual rule, bottom edge of the frame 20-25 cm above the sofa back, would hang the painting too high here, in a room built entirely on low lines: the marble coffee table, the stool, the floor cushion. On a sofa this low, 15 cm above the back is enough to separate the painting from the cushions without letting it float in the middle of a tall wall.

The painting stays centred on the sofa, not on the wall: the niche to the left would throw off a composition centred on the full width of the wall.

What size for a double portrait at this scale?

Jacques and Berthe Lipchitz, by Amedeo Modigliani is a vertical portrait built around two figures: a size that stays vertical when framed, at 50 x 70 cm or 75 x 100 cm, keeps the original proportion without forcing a recrop of the composition. A square-leaning format would have added an unnecessary margin at the top or bottom.

The eight moulding tones available for this print, from natural oak to black, are photographed side by side on the materials page: on a clay-coloured wall, a moulding darker than the wall, walnut or black, keeps the frame readable without echoing the brick tone of the sofa.

What about the child's drawing on the opposite wall?

Nothing to fix. A child's drawing taped low on one wall and a museum-grade framed painting on the main wall are not competing, because they are not playing the same role in the room: one is a lived-in piece, the other a chosen one. Trying to match them, by framing the drawing or removing it, takes away exactly what makes the room feel lived in rather than staged.

• Arched niche: an object placed inside it, never a rectangular frame.
• Low sofa (under 75 cm back height): bottom edge of the frame 15 cm above it, not 20-25 cm.
• Vertical double portrait: a vertical size, 50 x 70 or 75 x 100, never a square-leaning format.
• Clay or sand-toned wall: a moulding darker than the wall, dark oak, walnut or black.
