How to print photos for resin moulds

By CraftCrop · Updated 4 November 2026

Use this quick guide to move from a customer photo to a sheet you can print and cut for a resin mould or small handmade keepsake.

1. Choose your paper

Select 4 × 6 inch photo paper or A4 and choose portrait or landscape. Keep your shapes inside the dotted safe area; printable margins vary by printer.

2. Set the mould size

Choose a shape and enter the real measurement in centimetres. For circles, enter the diameter. For squares, enter the side length. For ovals, rectangles, and hearts, enter width and height.

3. Add and crop photos

Select one or more images from your device. Drag each shape to arrange it. Select a shape to zoom, rotate, replace, duplicate, or move the photo crop inside it. The black outline marks the cut edge.

4. Download and print at actual size

Download the print PDF for the selected paper dimensions or the 300 DPI PNG. In the print dialog, choose the matching paper size, select “Actual size” or “100%,” and disable “Fit to page” or other scaling. Check one shape with a ruler before making a full batch.

Example: a 5.5 cm round photo order

Measure the space where the photo will sit, choose Circle and enter 5.5 cm. Add the original customer image and centre the face inside the circle. Duplicate the finished shape if you need matching inserts, then keep every copy inside the sheet margin. Print one test sheet at 100% and measure the circle across its widest point: it should be 55 mm. Check the fit in your own mould before preparing the remaining order.

Photo clarity

At 300 DPI, a 5 cm circle needs roughly 591 pixels across for a full-resolution source image. If the original is smaller, the print may look soft even though the sheet itself is exported at 300 DPI.
