The most readable locker decals use a bold, simple sans-serif font, high contrast against the locker paint, and a consistent placement on every door. Numbers between 2 and 4 inches tall stay legible down a hallway without crowding out combination instructions, name cards, or vents.
Contrast and finish. Pair dark lockers with white or yellow numbers and light lockers with black or navy. A matte laminate cuts glare from overhead hallway lighting, which keeps numbers easy to read from an angle.
Placement. Mount numbers in the same spot on every door, typically centered above the vents or at eye level on the upper third. Consistent placement lets students and staff scan a row of lockers in seconds.
Color coding. Many schools color code by grade level, wing, or team. Submit one layout file and request a different accent color for each group, which keeps production simple while giving each hallway a distinct look.
Sequential numbering. For hundreds of lockers, send a simple spreadsheet or numbered list with your artwork so every decal in the run prints with its own number, in order and ready to install.
Clear-backed options. On lockers with brand-new or brightly painted finishes,
clear decals let the locker color show around printed numbers and logos.
File setup. Vector files (EPS or AI) with fonts converted to outlines print and cut the sharpest. For transfer-cut numbers and lettering, keep text at least 1/2 inch tall with at least 1/8 inch between characters. Review the Decals.com

custom decal design best practices before submitting your file.
Schools that want words instead of numbers, such as homeroom names, department labels, or a hallway motto, can use cut vinyl lettering for a clean, painted-on look.
