Armor Class

Your Armor Class (AC) measures how well you can defend against attacks. When a creature attacks you, your AC is the DC for that attack roll.

AC = 10 + Dexterity modifier (up to armor’s Dex Cap) + proficiency bonus + armor’s item bonus to AC + other bonuses + penalties

Use your proficiency bonus for the armor’s category (light, medium, heavy) or the specific armor type. If not wearing armor, use your unarmored defense proficiency.
