What Size Photo Fits in a Locket? A Practical Guide

There is no single standard size for a locket photograph. The measurement that matters is the recessed space inside the locket—not the outside width of the jewellery.

width

Measure the widest inner point

Use the photograph recess or removable insert, not the outside edge.

height

Check the usable height too

Heart, oval and rectangular openings have different proportions.

If the shape is awkward, place thin paper over the recess and mark the inner edge gently. A removable clear insert is normally the most accurate template; never force out an old or delicate insert.

Why one sheet contains 34 prints

Instead of asking you to order one exact measurement, Featherlings prints two copies of 17 approximate widths. Choose the smallest print that still covers your paper template, then trim it gradually.

♥

Heart

For heart openings, including small vintage lockets with a deep centre notch.

○

Oval or round

For traditional oval lockets and circular photograph openings.

□

Any shape

For rectangles, unusual proportions and lockets that need a custom paper template.

Vintage lockets in many different shapes and proportions — Similar-looking lockets can be completely different inside.

Open heart locket with two differently cropped photographs — The right crop matters as much as the millimetre measurement.

Choose a photograph that can survive the crop

Use a clear original image with the important subject near the centre and some space around the face. A tightly cropped phone photograph can lose part of the head when cut into a heart or oval. Use the on-page editor to move, zoom and rotate the image before confirming it.

Small locket? One clear face will usually work better than a large group. The second copy of every size gives you a spare attempt if the first crop is not quite right.

Do the prints arrive cut out?

No. You receive the complete sheet so you can compare sizes against your own locket and trim the best match. This is more reliable than assuming the external dimensions match the photograph opening.
