Base Armor Class 5e: How to Calculate

Base Armor Class 5e: How to Calculate

Armor Class in DnD 5e can sometimes be a bit confusing for new players. There are a lot of numbers and modifiers flying around, as well as types of armor to consider. The good news is that calculating Base AC is super simple and barely even counts as math.

To find out what your base AC is, all you do is start with 10 and add your DEX modifier from the left side of your character sheet.

Base AC = 10 + Dexterity Modifier

That’s it! Now you know your Base AC and can build on your Armor Class from there.

Your character’s AC is affected by what type of armor you wear, spell effects, or an ability that your character has. Check out our list of Armor in DnD 5e or our Mage Armor spell guide to learn more.
