Framing and Mounting Ideas
Frames and mounts protect posters and make them look better. Pick a frame that’s 1 inch bigger than the poster. Add a mat with an opening slightly smaller than the poster for a clean look. Mounting on foamboard keeps the poster flat and prevents bending.
Foamboard is cheap and keeps posters smooth.
Don’t dry-mount collectible posters to keep their value.
Thin paper may need extra support to avoid wrinkles.

Lighting helps your poster stand out. Use spotlights or LED lights to highlight it. Avoid direct sunlight, as it can fade the colors over time.
Tip: Try warm or cool lights to match your poster’s colors and set the mood.
A 20×30 poster is a great size for businesses. It’s big enough to be seen but easy to move. The 2:3 ratio makes designs look neat and professional. You can use it for ads, events, or office decor.
