In the United States, size designations are frequently expressed by a code of the type nR, where n specifies the length of the shorter edge in inches. The length of the long edge in the standard series equals the length of the short edge plus 2 inches (10 in or less) or 3 inches (11 in and above). For example, a photo that is 4 inches by 6 inches uses the code 42.
In Europe, size is usually indicated by two numbers, for example, 545 or 864 × 1242. The first number indicates the width of the image in millimeters, while the second number indicates its height in millimeters. These numbers are often written out in words to avoid confusion: "0545" or "0864 x 1242".
In Japan, sizes are generally given in square meters with decimal points. For example, an image that is 1 meter by 2 meters uses the code 100.200.
Photo sizing software can help you determine the code for a given size system, although some countries use different systems. For example, the United States uses a decimal system for small images up to 4 by 6 inches, after which they become too large to be coded by picture number.
In Canada, image sizes are expressed in units of inches based on the width of the image. For example, a photo that is 4 inches by 6 inches uses the code 46.
The longer side is 2 inches longer than the shorter side for 10 inches and under. The longer side is 3 inches longer than the shorter side for sizes 11 and above. Here is a pricing list for our R picture sizes. If you want to print your images, here's a guide to the resolution you'll need. 468 pixels per inch (ppi) is good enough for most people. Anything better and you're paying for pixel density over quality.
Your best bet is to print a few sample photos at different sizes to see which one looks best on your wall.
This article explains in detail how big a photo is printed on paper stock of various sizes. It's also important to note that the size of the photo itself doesn't matter so much as the size of the overall image relative to your wall space. A large image on a small wall will look bad, but a small image on a large wall will look fine.
There are two types of photo frames: those that hold only one photograph and those that hold many. Single-photograph frames usually contain glass or plastic that allows you to see the entire image, while multiple-image frames often consist of several smaller photographs mounted on a backing material that fits behind the glass or plastic. There are three main types of backings used with multiple-image frames: matting, filigree, and shadowbox. Matting is a thin layer of wood or other material that covers the entire back of the frame.
R series—Standard Photographic Sizes
|3R||3.5 x 5||8.89 x 12.7|
|4R||4 x 6||10.2 x 15.2|
|5R||5 x 7||12.7 x 17.8|
|6R||6 x 8||15.2 x 20.3|
Yes, 4x6 is the most frequent and conventional 35mm image format. Other sizes include 5x7, 8x10, 8.5x11 (letter size), 11x14, 16x20, 24x36, and so on. There are a lot more in between normal sizes that aren't as frequent. For example, an 18x24 canvas would be two times six inches wide and three-and-a-half inches high.
However, not all images need to be standard sizes. If you want to experiment with different shapes, go for it! As long as they don't overlap too much, anything goes.
There's no right or wrong here. Use what feels right for your image.
Photo Print Sizes: Standard (R), Square (S), and A4
|2R||2.5 x 3.5||63.5 x 88.9|
|4S||4 x 4||102 x 102|
|4R||4 x 6||102 x 152|
|5R||5 x 7||127 x 178|
It's measured in millimeters, exactly like the focal length of a camera, and may be found next to the o sign, which stands for diameter. The lens diameter is usually inscribed on the front of the camera lens, or on the side at the top, where you'd screw on your lens filter. Sometimes it's also printed on small labels attached to the sides of the lens barrel; if you have trouble locating it, ask an associate or customer service representative at your local store.
Here are some examples of common lens sizes with their corresponding values: 50mm = 25.4mm, 85mm = 34.9mm, 100-400mm = 57.5mm, 1.4-12mm = 7.7mm.
For measuring your own lens, you can use a ruler or thin piece of cardboard as a guide. Make sure not to cover up any markings on the lens.
If you don't know your actual lens size, you can estimate it by using this formula: (distance from center of lens - distance from edge of lens) x 4.5mm.
So, if your lens is 200mm then it has a inner diameter of 93.5mm, and if it has a macro capability of 1:1, then its minimum focusing distance should be 93.5mm as well.
