Tea Steeping Ratio Calculator

About this calculator

Tea strength comes down to a leaf-to-water ratio, typically expressed in grams of loose-leaf tea per volume of water — a common baseline is around 2-3 grams per 200ml (roughly 1 gram per 100ml), though the right ratio shifts by tea type: delicate green and white teas are usually brewed lighter, while robust black teas and dense oolongs can take a stronger ratio without turning bitter.

Tea professionals and serious home brewers treat this ratio as one of the two variables (along with water temperature and steep time) that most determine cup quality, since too little leaf produces a thin, underextracted cup while too much leaf over-extracts tannins into bitterness regardless of steep time. Cafés and tea houses standardize their ratios precisely so that a pot of the same tea tastes consistent from one order to the next, rather than varying with whoever happens to be scooping the leaves.

Enter your water volume and desired strength, and this calculator tells you how many grams of loose-leaf tea to use.
