Tea ratio calculator

How the ratio works

The calculator works in both directions using a ratio of millilitres per gram. Each tea type has its own starting ratio for light, medium, and strong brews:

• I have tea: multiply your tea grams by the ratio to get the water you need.
• I have water: divide your water millilitres by the ratio to get the tea you need.
• Sugar: calculated from the water amount at a fixed grams-per-250 ml level for your chosen sweetness.
• Time and temperature: shown as simple guidance for that tea type.

Matcha is whisked rather than steeped, and cold brew tea steeps in the fridge for several hours — the recipe reflects that instead of a hot steep.

Tea types covered

The calculator supports black, green, white, oolong, herbal, rooibos, matcha, and cold-brew tea. Each result includes a tea-to-water starting ratio plus time and temperature guidance for the selected type; matcha is shown as whisked rather than steeped.

Method and sources

The calculator converts a selected ratio into a starting amount. Its ratios, strength profiles, time and temperature ranges are Yusr editorial starting presets, not universal preparation rules or a single authority’s standard. Leaf size, tea and brand, water temperature, equipment, region, and taste can change a good result.

For comparison, Twinings’ brewing guide publishes different brew times for tea types and advises adjusting the amount of tea and steeping time to taste. Follow a producer’s directions when they are available for your specific tea. The calculator’s sweetness values are optional Yusr preference presets only; Twinings likewise describes milk and sugar as matters of personal taste.

Example

3 g of medium-strength black tea gives 300 ml of water, and 300 ml of the same tea gives 3 g of tea. At medium sweetness that adds about 6 g of sugar, or roughly 1.5 level teaspoons (1 teaspoon ≈ 4 g). The same 3 g as medium matcha gives only 120 ml, because matcha uses much less water per gram.

Privacy

Everything is calculated in your browser. Your tea or water amount and your choices are never stored or sent to a server, and the tool makes no network requests.

Limitations

The ratios are common starting points, not universal rules. Strength depends on your tea, brand, leaf size, water temperature, and taste. Sugar preferences vary a lot, so the sugar result is optional guidance, not a requirement. Treat the result as a first recipe to adjust.

Quick tips

Start with medium strength and no sugar. If the cup tastes weak, move one step toward strong; if it tastes too intense or bitter, move toward light or shorten the steeping time. For green and white tea, avoid boiling water so the leaves don't turn bitter.
