Margins are one of the most important settings in Photoshop. They can make or break a photo, so it’s important to know how to set them correctly. There are three types of margins: content, border, and padding. Content margins are the ones that affect the content of your photo. Border margins are the ones that affect the edge of your photo. Padding margins are the ones that add space between your photo and the surrounding text or image. To set a margin, open Photoshop and select Image > Margins… from the menu bar. The Margins dialog box will open. In this dialog box, you’ll first need to decide what type of margin you want to set: content, border, or padding. Then, you’ll need to enter values for each type of margin. Here’s a breakdown of each type: Content Margins: The first value is for the left margin (L), and the second value is for the right margin (R). These values can be any number you want, but be sure to keep them within Photoshop’s limits—you won’t be able to go too high or too low on either side. Border Margins: The first value is for the top margin (T), and the second value is for the bottom margin (B). Again, these values can be any number you want, but be sure to keep them within Photoshop’s limits—you won’t be able to go too high or too low on either side. Padding Margins: The first value is for how much space there should be between your photo and surrounding text or images (W), and the second value is for how much space there should be between your photo and its own borders (H). Again, these values can be any number you want, but be sure not to go over Photoshop’s limits—you’ll get an error message telling you so! ..
