Whether you run a gift shop, photo studio, or online store, stocking the right picture frame sizes is key to keeping customers happy and maximising sales. The most popular frame sizes cater correctly to standard photo prints while suiting familiar spaces like desks and walls, as well as common gifting occasions.

In this guide, we’ll break down the most popular photo frame sizes in the US, the difference between similar-sounding dimensions, how mounts affect frame sizing, and why it’s still worth keeping a few non-standard options on your shelves.

What Are the Most Common Frame Sizes in the US?

For everyday photos, gifts, and décor, these are the standard picture frame sizes in the US:

These are the common picture frame sizes that dominate US retailers, as they align with standard photo printing dimensions and consumer expectations. Offering frames in these sizes ensures your stock is practical and widely appealing.

Are Most Photos 4x6 or 5x7?

4x6 inches (10x15 cm) is by far the most common photo size, especially for home printing, photolab orders, and instant print kiosks. It’s also the default layout of most digital cameras and smartphones.

That said, 5x7 inches (13 x 18 cm) is a close second, offering a bit more impact for display or gifting, without taking up too much space.

If you're stocking frames for general retail, both 4x6 and 5x7 should be your baseline.

Is There a Difference Between 5x7 and 7x5?

While the dimensions are technically the same, the orientation isn't, and that matters for packaging, display, and customer clarity. So, yes, there is a difference between 5x7 and 7x5 photo frames, and it’s an important distinction to understand, especially when dealing with portrait vs. landscape orientation.

  • 5x7 typically means portrait orientation (5 inches wide, 7 inches tall).
  • 7x5 usually refers to landscape (7 inches wide, 5 inches tall).

The same applies to other sizes like:

  • 4x6 vs. 6x4
  • 6x8 vs. 8x6
  • 8x10 vs. 10x8

Always list both the size and the orientation where possible. Some retailers go as far as labelling their products with small icons or descriptors like "Portrait" or "Landscape" to avoid confusion.

Frame Size vs Mount Size

Picture frame sizes can get confusing, especially when the numbers on the label don’t seem to match the photo you’re trying to frame. Here’s why: the frame size usually refers to the outer size of the mount or the space inside the frame, not the size of the photo it holds.

For example, a frame might be sold as 8x10 inches, but if it comes with a mount (the border that sits around the photo), the actual visible area might only fit a 5x7-inch photo. The mount border takes up some of that space, and that’s intentional, to make your photo look better and protect it from touching the glass.

If you’re selling or buying mounted frames, it’s useful to understand three key terms:

  • Print size: The size of the photo/art that will go inside
  • Mount aperture size: The size of the opening in the mount
  • Overall frame size: The outer edge-to-edge dimensions of the frame

Retailers should be clear on what size the customer’s image should be, especially when mounts are involved. Offering a mix of unmounted and mounted frame options can help cover more customer needs.

What Are Some Non-Standard Frame Sizes?

While stocking standard photo frame sizes is essential, there’s a growing demand for non-traditional formats, especially among artists, social media users, and gifting audiences. 

These include:

  • Square frames: 4x4, 8x8, or 12x12 square photo frame options are great for Instagram-style prints and photo collages
  • Panoramic frames: For example, 10x20 inches, ideal for landscapes or group shots
  • Polaroid-style sizes: Frames with space for a caption or border
  • Custom or shaped frames: Hearts, stars, circles - often made from acrylic for gifting

These non-standard options can set your product line apart, especially around seasonal gifting events or with personalized photo gifts.
