6. Practical Tips and Best Practices

Mastering the use of a 3.5 x 4 size is easier with a few pro tips:

  • Download Templates: Request a template from your print provider so your design lines up perfectly.
  • Include Margins: Leave a safe margin (usually 0.125 inches) around the edge for cutting.

B. For Photos

  • Cropping: Before printing, crop your images exactly to 3.5 x 4 inches to avoid unwanted borders or stretching.
  • Test Print: Always do a test print on plain paper first to confirm the size and alignment.

C. For Crafts and Custom Products

  • Measure Twice, Cut Once: Use a ruler and template to ensure precise cuts if creating by hand.
  • Adhesive Backings: If making magnets or stickers, leave room at the edges for adhesive, especially if the print will be handled frequently.
