The D&D Carrying Capacity Calculator turns a Strength score into every weight limit the 5th edition rules define: how much you can carry, how much you can push or drag, and the optional encumbrance thresholds. It applies the right size multiplier automatically so mounts, ogres, and Tiny familiars all come out correct.
How it works
In 5e your carrying capacity is simply your Strength score times 15 pounds. Past that you cannot pick up more gear without dropping something. The push, drag, or lift maximum is Strength times 30 — twice your capacity — but moving a load that heavy halves your speed.
Creature size scales everything by a fixed factor: Tiny halves the result, Large doubles it, Huge multiplies by four, and Gargantuan by eight. The tool applies that multiplier to all four figures.
Variant encumbrance
If your table uses the optional encumbrance rule from the Player’s Handbook, two extra thresholds matter. You become encumbered when carrying more than Strength times 5 pounds, dropping your speed by 10 ft. You become heavily encumbered above Strength times 10 pounds, losing 20 ft of speed and gaining disadvantage on attack rolls, saving throws, and ability checks that use Strength, Dexterity, or Constitution.
Example and notes
A fighter with Strength 16 has a 240 lb carrying capacity and can push or drag up to 480 lb. Under the variant rule they slow down past 80 lb and become heavily burdened past 160 lb. Remember that standard play ignores these middle thresholds entirely — track them only if your group opts in.
