A pattern repeat tester is a tool that lets you upload a single pattern tile and preview how it looks when tiled repeatedly across a surface. It shows you whether your design repeats seamlessly before you commit to printing, uploading to a print-on-demand platform, or sharing with a client.

Click anywhere on the preview area or drag and drop your image file directly onto it. Your pattern tile will instantly tile across the canvas. Use the scale slider to zoom in or out, and switch between repeat modes to test different layouts. When you're happy with what you see, hit Save to download a preview image.

This tool accepts PNG, JPG, and SVG files. It works with tiles exported directly from Procreate, Photoshop, Illustrator, Canva, or any other design app.

You can test three repeat types: straight repeat (standard grid), half-drop vertical (each column shifts down by half a tile), and half-drop horizontal (each row shifts right by half a tile, also called a brick repeat). These are the most common repeat structures used in surface pattern design, fabric, wallpaper, and stationery.

A half-drop repeat is a pattern layout where alternating rows or columns are offset by half the height or width of the tile. It's one of the most popular repeat structures in surface pattern design because it creates a more natural, flowing look compared to a straight grid repeat. Vertical half-drop is common in fabric and wallpaper design. Horizontal half-drop (brick repeat) is often used in tile and stationery design.
