Why Picture Frame Size Matters
Choosing the wrong frame size can make a beautiful photo look awkward or underwhelming. The size of your frame not only affects the visual balance of your display, but also how your image interacts with its surroundings.
Whether you’re framing for a minimalist look or creating a bold, layered gallery wall, matching the right size ensures:
- A professional, polished appearance
- Proper fit with or without matting
- Cohesion with furniture, decor, and layout
- Easier hanging and alignment
Let’s dive into the sizes that work best—and when to use them.

Standard Picture Frame Sizes
Here are the most common frame sizes you’ll come across for both photos and artwork:
| Photo Size | Frame Size (No Mat) | Frame Size (With Mat) |
|---|---|---|
| 4″ x 6″ | 4″ x 6″ | 5″ x 7″ or 6″ x 8″ |
| 5″ x 7″ | 5″ x 7″ | 8″ x 10″ |
| 8″ x 10″ | 8″ x 10″ | 11″ x 14″ |
| 11″ x 14″ | 11″ x 14″ | 16″ x 20″ |
| 16″ x 20″ | 16″ x 20″ | 20″ x 24″ |
| 18″ x 24″ | 18″ x 24″ | 24″ x 30″ |
| 24″ x 36″ | 24″ x 36″ | 30″ x 40″ or custom |
These sizes are widely available at craft stores, home goods retailers, and online shops, and work well for portraits, travel photos, event shots, and posters.
What Is Matting and Why Does It Matter?
Matting is the white (or colored) border between the photo and the edge of the frame. It:
- Adds visual space around your photo
- Prevents contact between the glass and image
- Elevates the look of any print
- Helps small photos fit in larger frames
For example, an 8″ x 10″ photo might be matted inside an 11″ x 14″ frame. It creates breathing room and draws attention to the photo.
If you’re going for a gallery aesthetic or museum-style display, matting is your best friend.
Frame Size vs. Image Size vs. Mat Opening
Let’s clarify the difference between three essential dimensions:
- Image Size: The actual size of your photo or art print
- Mat Opening: The inner cutout of the mat (usually slightly smaller than the photo to hold it in place)
- Frame Size: The outer dimensions of the frame (based on the glass or mat board area)
Tip: Mat openings are typically ¼ inch smaller than the image size to prevent slipping. For example, a mat opening for a 5″ x 7″ photo might actually be 4.75″ x 6.75″.
Best Picture Frame Sizes for Common Uses
Here are the ideal sizes for some of the most popular framing needs:
1. Portrait Photos

2. Wedding & Event Photos

- Digital designs you print at home

Matching Frame Size to Room Style
✅ Small Frames (4″ x 6″, 5″ x 7″)
- Great for desks, shelves, nightstands
- Ideal for intimate spaces like bedrooms or nooks
✅ Medium Frames (8″ x 10″, 11″ x 14″)
- Balance well on walls without overwhelming them
- Work in entryways, kitchens, hallways
✅ Large Frames (16″ x 20″ and up)
- Add a statement in living rooms and staircases
- Combine with mats for a gallery or upscale feel
How to Measure a Picture for Framing
- Measure the image size (width × height).
- Decide if you want to include a mat.
- Choose a frame size that matches either the image size (no mat) or the outer mat size (with mat).
- Double-check frame depth if you’re framing canvas or textured artwork.
Pro Tip: Lay your image flat and use a ruler for accuracy. Round up to the next standard frame size if your photo has white borders or if you plan to crop.
Tips for Arranging Multiple Frames
- Symmetry works well with same-sized frames
- Asymmetry adds a modern touch with mixed sizes
- Use paper templates to lay out your gallery wall before hanging
- Keep spacing consistent—usually 2″ between frames
Frame Styles That Match Every Size
Different frame sizes pair well with specific styles:
| Frame Style | Works Best With |
|---|---|
| Thin Black Metal | Modern, minimalist photos |
| Wide Wood Frame | Large art, rustic or traditional rooms |
| Floating Frame | Canvas prints, modern decor |
| Ornate Vintage Frame | Portraits, wedding photos |
Experimenting with styles adds character to any space. Whether you go for a clean Scandinavian look or a cozy farmhouse vibe, there’s a frame for that.
