How to Frame a Paint-by-Numbers Canvas

To frame a paint-by-numbers painting, first check what it’s painted on. Paper needs a backing and space behind the glass. A canvas on wooden bars needs a frame deep enough to hold those bars. Measure the finished piece before you order: the size printed on a kit doesn’t tell you how much of the picture a frame will cover.

Finish touch-ups and let the paint dry

Check for unpainted gaps in even light and make any small corrections before adding a finish. Let the work dry according to the materials you used. Avoid placing the painted face on a table while handling or measuring it.

Varnishing is a separate decision from framing. Follow your varnish maker’s drying times: a touch-dry surface may need longer. Liquitex’s acrylic varnishing guidance explains its products’ requirements. Try any finish on a separate sample first, especially if you want to preserve a matte look.

Choosing a frame for paper, board or canvas

• Paper or a painted printout: use a mount (also called a mat board) or spacers to keep the painted surface away from the glass or acrylic front panel. A backing board supports the sheet.
• Canvas board: measure the board’s thickness as well as its height and width. The frame needs room for the panel and its retaining hardware.
• Stretched canvas: choose a frame designed to accommodate the stretcher depth. A float frame leaves a visible gap around the canvas edge.
• Loose canvas: decide how it will be mounted or stretched before choosing the final frame. Keep the unpainted margin; it may be needed for stretching.

For traditional gouache on paper, Winsor & Newton recommends a glass frame with a mount to separate the work from the glass. Do not assume a varnish intended for acrylics is suitable for every painted printout.

How to measure for a picture frame

Write down the actual width, height, and depth, plus the area you want visible. A frame’s outer dimensions are not its artwork opening. Check how much the frame lip or mount will overlap the picture; a signature, ear, or flower near the edge can disappear behind it.

Fit the painting before fastening the back

Place the dry artwork in the frame as its instructions show. Check the front before fastening anything: is the picture level, and are the important edges still visible? On paper, keep the mount or spacers between the painted surface and the glass. Use the frame’s supplied fittings to hold the work in place. If the back will not close comfortably, check the depth instead of forcing it.

Choosing a frame colour

Try one simple option first: pale wood, dark wood, black, or white. Hold a sample beside the picture and look from across the room. With a detailed picture, a plain frame is a useful starting point. A dark frame may work well if the painting already has dark outlines or shadows. You do not need to match every palette colour.

Hanging your finished painting

Choose a place away from splashes, persistent damp, and direct sunlight. Use hanging hardware rated for the assembled frame’s weight and suitable for your wall. For a gift, add a note with the photo’s story and the date you finished painting; the gift guide has more presentation ideas.

Planning your next piece? Decide on its display size before you transfer a numbered design to canvas. Keeping the future frame in mind makes the final step much easier.
