10 Best Free Online Depth of Field Calculator Websites

Here is a list of the best free online depth of field calculator websites. In photography, depth of field is the distance between the nearest and the farthest objects that are in focus. It is an important factor in photography that can lead to amazing results. Maximizing the depth of field can give you sharper photos. Whereas keeping it shallow gives you a natural background blur and separates the object from whatever is behind. Depth of field depends on the camera hardware/sensor. To calculate the depth of field, you need to know the focal length, aperture, subject distance, etc.

This post covers 10 free websites that provide you with a depth of field calculator. You can simply open a calculator and pick your camera type or the negative format that you use. Then you can enter just enter the required information to get the total depth of field. Some of these websites offer additional information along with the depth of field. This can further help understand the scenario and thus improve your photos. With that said, let’s check out these websites one by one in detail.
