Picture frames are categorized into standard and non-standard sizes. Standard sizes are more common and typically correspond with standard photo sizes. Frames in the United States are measured in inches, while most other parts of the world use centimeters. Picture frames are always measured width by height. So, a 6" wide by 4" high photo would be considered 6x4; however, if your photo measured 4" wide by 6" high, it would be a 4x6 photo. What sometimes confuses people is that some frames like 4x6, 5x7 or 8x10 picture frames can usually be used as either a vertical or a horizontal frame. However, when you see sizes like 6x4, 7x5, 10x8 this means that they can only be used horizontally.
What to Look For When Buying a Frame-
1) Before you buy a picture frame first determine the size and direction of your photo. Picture frame sizes represent the size of the picture the frame will hold, not the overall size of the frame. If you were to measure a frame, you would measure the inner opening rather than the outer edge of the frame. Don't worry if your frame measurement is not exactly a standard size. In order for the picture to fit properly in the frame, the glass and picture fit onto a thin ledge and the outside frame hides the edge of your picture. If you want a truly accurate measurement of your frame, remove the back and measure the size of the glass.
2) Some frames are only displayed in one direction. Before you buy a frame determine how you want to place it. You will know by the shape of a frame if it can only be displayed in one direction. For example, a heart shape is a great example of a frame that can only be used in one direction. Decorations are another way to tell if you have a frame that can only be used in one direction. For example if you have a vertical 8x10 picture frame with a image of a tree decorated on the frame, that frame can only be used vertically otherwise the tree won't be standing upright. Also check the easel on the back to see if it can be displayed as both a vertical and horizontal frame.
3) Always check the back of the frame to see how it can be used. Never assume a frame comes with either an easel back stand or picture frame hanging hardware. If you plan to use it on a desktop always check that it has a easel back stand or if you're hanging it on the wall make sure it has frame hardware secured on the back of the frame.
Picture Frame Sizes-
There is a noticeable difference in availability between standard frame sizes and less common frame sizes. Standard (or common) frame sizes are readily available and usually offer a big selection to choose from. They're often referred to as standard frame sizes because photos or certificates are commonly printed in these sizes. You can find the uncommon sizes but they'll usually have less variety in color and style compared to the common sizes.
Here is a list of the most common frame sizes along with the list of less common (or uncommon) frames that can be found but often have more limited selections. Often times, if you have a specific need for an uncommon size, you may need a custom frame if the size you are looking for is not listed below.
Common frame sizes 2 x 3 (wallet size), 3 x 5, 4x6 (vertical or horizontal), 5x5, 5x7,6x4 (a 4x6 standing horizontal), 6x8, 8x10, 7x5 (a 5x7 standing horizontal), 10x8 (8x10 standing horizontal), 8 x 11 (certificate size), 11x14 16x20 and 20x24.
Less Common Frame Sizes 1x2, 2x2, 2x3, 3x3, 3 x 3 , 3x4, 3 x 10 (panoramic), 4x4, 4x5, 4x10 (panoramic), 4x12 (panoramic), 8x8, 8x12, 10x10, 10x13 and 12x12.
Other commonly found frames are doubles, triples, multi or collage picture frames.
Double picture frames have two identical openings that normally fit up to 8x10 size pictures and are often used for portraits. Triple picture frames have three identical openings and normally fit up to 5x7 size pictures. Triple 8x10 frames aren't as common due to the large size of the frame.
Now for the fun frames - the multi picture frame or collage frame. As named, multi picture frames have multiple openings or windows. They are often called collage picture frames because they can display a variety of pictures and sizes. This type frame is perfect for those special pictures you want grouped together on your wall.
Hopefully this article will help you better understand what to look for when buying a frame and how to find the right size so you'll always find the perfect frame.
