What Size Should My Portrait Be? A Room-by-Room Guide
Choosing a size is the question that stalls a lot of portrait commissions — but it's simpler than it feels. Size comes down to two things: how many subjects are in the painting, and where it's going to hang. Get those two right and the rest follows. Here's a clear, room-by-room guide, plus one rule of thumb that prevents the most common regret.
The one rule that prevents regret
When in doubt, go one size larger than feels obvious. Nearly everyone underestimates how a portrait will read on the wall. A canvas that looks generous in your hands or on a screen often looks modest once it's hung, especially above furniture or on a large wall. Undersized portraits are the single most common sizing regret; oversized ones are rare. So if you're torn between two sizes, the larger one is usually the safer choice.
A quick size map
These are general ranges — exact options vary, but this gives you the feel:
- Small (around 16×20 inches): A single subject at intimate scale. Perfect for a desk, a shelf, a bedside, or as part of a small gallery wall. Lovely, but it won't command a large empty wall on its own.
- Medium (about 18×24 to 24×30 inches): The versatile "focal point" size. Holds its own over a console table, in a hallway, or on a bedroom wall. A strong default for one or two subjects.
- Large (30×40 inches and up): The statement piece. This is what you hang above a fireplace, a sofa, or a stairwell — the portrait meant to anchor a room and gather the family's eye. Ideal for groups, families, and heirloom pieces.
Room by room
Above a fireplace or mantel. This is the place of honor, and it wants presence — go large (30×40 inches or bigger for groups). A small portrait here looks lost above the weight of a mantel.
Over a sofa or console. Aim for a width that's roughly two-thirds the width of the furniture below it. For most sofas, that lands in the medium-to-large range. Centered and not too high — the middle of the painting around eye level.
In an entryway or hallway. A medium portrait makes a warm first impression without overwhelming a narrow space. This is a wonderful spot for a single subject or a couple.
In a bedroom or study. More intimate, so small-to-medium works beautifully — something you see up close rather than across a room.
As part of a gallery wall. Smaller sizes shine here, grouped with other framed pieces. If the portrait is meant to be the anchor of the grouping, size it noticeably larger than the pieces around it.
How many subjects changes the size
The more people or pets in the painting, the larger it needs to be for each face to be rendered with detail and dignity. A single portrait can be intimate at a smaller size; a family of four or five really wants a medium-to-large canvas so no one is reduced to a thumbnail. As a rough guide, step up one size for every couple of additional subjects.
A note on cost
Size is the biggest single factor in what a portrait costs, since a larger canvas means more hours and materials. That's worth knowing as you choose — but don't let it push you to undersize a piece you'll live with for decades. The right move is usually to pick the size the wall and the moment deserve, then choose framing and subjects to fit your budget. Our cost guide breaks down the trade-offs honestly.
