How To Measure Photo Frame Size

Ever bought a photo frame online, only to find it’s completely the wrong size when it arrives? We’ve all been there! Determining the correct size frame for your precious photos or artwork is crucial, not just for aesthetics, but also for preserving the integrity of your memories. A frame that's too small will cut off important details, while one that's too large can make the image appear lost and insignificant. Getting it right ensures your treasured moments are displayed in the best possible light and protected from dust, damage, and fading. Whether you're framing a family portrait, a stunning landscape, or a child's artwork, understanding how to accurately measure for a photo frame is a skill that will serve you well for years to come.

Accurate measurement is the foundation for selecting the ideal frame, matting, and mounting options. It prevents unnecessary returns, saves time and frustration, and ultimately enhances the visual impact of your displayed items. Beyond simply knowing the dimensions, understanding the different types of measurements – image size, frame size, and mat window size – is key to achieving a professional and polished look. So, grab your measuring tape and let’s dive into the world of photo frame sizing!

What do I need to know about measuring my image and the frame?

How do I determine the correct photo frame size for my picture?

The correct photo frame size is determined by matching the *inside* dimensions of the frame to the *outside* dimensions of your picture. Measure the height and width of your photo, and then look for a frame with those same inside dimensions. For example, a 5x7 inch photo requires a frame that is exactly 5 inches wide and 7 inches high (inside the lip where the photo sits).

To elaborate, remember that frame sizes are always described by the dimensions of the image they are designed to hold. The actual *outside* dimensions of the frame will be larger than the stated size, because they include the frame's border, or moulding. Don't be tempted to measure an existing frame you like from the outside to choose a new frame for a photo; you need to know what size picture it *holds*. If your photo has a border or you want a mat to surround the photo within the frame, you will need to account for those additional dimensions. A mat will partially cover the edges of your photo, typically by about 1/4 inch on each side. This means you'll want to choose a mat opening slightly smaller than the photo dimensions, and a frame size that matches the *outside* dimensions of the mat. For example, if you have an 8x10 photo and want a 2-inch wide mat, you'll likely need a frame that accommodates an 11x14 inch mat.

Should I measure the inside or outside of the frame to find its size?

Measure the *inside* of the frame to determine its size. This measurement indicates the size of the picture or artwork that will fit correctly within the frame. The outside dimensions are relevant for space considerations on a wall or shelf, but not for determining what size image to use.

The inside measurement, also known as the "sight size," represents the visible area within the frame. This is the critical dimension for ensuring your artwork or photograph is properly displayed without being obscured by the frame's edges. If you purchase a frame described as "8x10," it means an 8-inch by 10-inch image should fit perfectly inside the frame's opening.

The outside dimensions of the frame, including the width of the frame itself (the "frame width"), are important when considering where to hang the framed artwork. These external measurements help you determine if the frame will fit in a particular space on a wall or shelf. However, when matching a frame to a picture, always prioritize the interior dimensions. If the opening is smaller than the picture, the edges of the image will be hidden, and if the opening is larger, there will be a gap between the picture and frame.

Here’s a quick summary:

What's the difference between photo size and frame size when measuring?

The photo size refers to the dimensions of the actual picture or artwork you want to display, while the frame size refers to the overall dimensions of the frame itself, including the border or molding that surrounds the photo. Essentially, the frame size will always be larger than the photo size to allow for the photo to fit inside with a bit of overlap and for the frame's structure itself.

When measuring for a photo frame, it's crucial to prioritize the photo size. You need to know the exact dimensions of your picture (height x width) to ensure it fits correctly within the frame. Frames are typically advertised and sold based on the photo size they are designed to hold. For example, a "4x6" frame is designed for a 4-inch by 6-inch photograph. The actual outer dimensions of the frame will be larger, often by an inch or two on each side, depending on the width of the frame's molding. Confusion can arise if you measure the frame's outer dimensions and assume that's the photo size it holds. Always measure the *photo* itself or, if buying a frame first, check the frame's specification explicitly stating the photo size it accommodates. Ignore the overall size of the frame and concentrate on the internal dimensions specified for the artwork or photo. This will save you from purchasing a frame that is either too small or too large for your intended picture.

How do I account for the frame's border when measuring for a photo?

To accurately account for the frame's border (also called the "rabbet") when determining the correct photo size, measure the visible area within the frame, not the overall outside dimensions. This visible area dictates the exact size of the photo you'll need.

When a frame is described as an "8x10" or "5x7", it refers to the photo size that *fits* inside the frame, *behind* the lip of the border. The frame's border overlaps the edges of the photo, holding it in place. Therefore, the visible area will always be slightly smaller than the stated frame size. If you simply cut a photo to match the frame's stated size (e.g., 8x10), you'll discover that the edges are covered by the frame's border. To find the *exact* visible area (and thus the correct photo size), insert a ruler or measuring tape into the back of the frame, measuring the length and width between the inside edges of the frame's border. This measurement, accurate to the nearest 1/16th of an inch, is the size your photo should be printed or trimmed to. For example, an "8x10" frame might only display 7.5 x 9.5 inches of the photo. It's always better to measure precisely than to rely solely on the stated frame size, especially with older or handcrafted frames, which can deviate slightly from standard dimensions.

Is it necessary to measure in inches, or are other units acceptable?

While inches are commonly used in the United States for measuring photo frame sizes, other units, such as centimeters or millimeters, are perfectly acceptable, especially in countries that use the metric system. The key is consistency and clarity: ensure you are using the same unit of measurement for all dimensions (length, width, and depth if applicable) and clearly specify the unit you are using when communicating measurements, whether buying online or having a frame custom-made.

The choice of unit often comes down to personal preference or the standard used in your region or the specific retailer you are dealing with. Many online retailers now offer the option to view product dimensions in both inches and centimeters. If you are ordering a custom frame, it's crucial to confirm with the framer which unit of measurement they prefer to avoid any misunderstandings and ensure a perfect fit for your photograph or artwork.

Regardless of the unit you choose, always double-check your measurements before placing an order. Miscommunication about the unit of measure can lead to costly mistakes and a frame that doesn't fit your picture. Clear and explicit communication about the units being used is essential, no matter if it is inches, centimeters, or millimeters.

What if my photo isn't a standard size; how do I measure the frame?

If your photo isn't a standard size, you'll need to measure the exact dimensions of the photo (height and width) to determine the frame size you need. Always measure to the nearest 1/8 of an inch for accuracy.

To elaborate, when dealing with non-standard sized photos, avoid assuming a standard frame will work. Use a ruler or measuring tape to carefully measure the height and width of your photo. Make sure to measure the *actual image* you want visible within the frame, not the edges of any surrounding border or paper if you intend to trim them. Write these measurements down; they represent the *inside* dimensions of the frame you'll need to order or look for. When selecting a frame, you have two options: find a frame that exactly matches your photo dimensions or choose a slightly larger frame and use a custom-cut mat to fill the gap. A mat board not only adds a professional touch but also prevents the photo from directly contacting the glass or acrylic of the frame, preserving the image quality long-term. If you choose a larger frame, be sure to calculate the mat opening to perfectly match your photo dimensions. For instance, if your photo is 5.5" x 7.5", you will need a frame opening that is *exactly* that size, or larger, with a mat cut to expose those dimensions. Finally, remember that some frames are sold by their *outside* dimensions, which is particularly relevant if you have limited wall space. Double-check the frame's specifications, especially if purchasing online, to confirm whether the listed dimensions refer to the inside (photo size) or outside (overall frame size). This will prevent any unwanted surprises when your frame arrives!

How does frame depth affect the measurement process?

Frame depth doesn't directly affect the process of measuring the *size* of a photo frame (i.e., its length and width), which is determined by the dimensions of the artwork or photo it's intended to hold and the outer dimensions of the frame itself. However, depth significantly impacts how the artwork *fits* within the frame, the overall aesthetic, and the type of hardware needed for hanging.

While length and width determine the visible area and where the frame will fit on a wall, depth dictates the space available for mounting the artwork, any mats used, the glazing (glass or acrylic), and the backing board. A frame with insufficient depth might not be able to accommodate thicker materials like stretched canvases or multiple layers of matting. Conversely, excessive depth, while not functionally problematic, can create an unnecessarily bulky appearance. The depth measurement is crucial for determining appropriate hanging hardware. A shallow frame might require flush-mounted hardware, while a deeper frame may benefit from D-rings or wire that allow for a more secure and balanced hang. Furthermore, if you're ordering custom mats or have a particularly thick piece of art, knowing the frame's depth helps ensure that everything fits snugly and securely within the frame, preventing damage or an unsightly bulging back.

And that's all there is to it! Measuring a photo frame really isn't so scary, is it? We hope this guide has helped you find the perfect frame for your cherished memories. Thanks for reading, and be sure to come back for more helpful tips and tricks!
