Ramen Broth Ratio Calculator
Build a bowl of ramen the right way — scale the soup, tare seasoning and noodles across any number of bowls with the classic ratios.
How it works
Soup per bowl = 380–450 ml by style · Tare = soup ÷ 9 (≈1:9) · Noodles = 120–130 g per bowl · Totals = per bowl × bowls
A bowl of ramen is assembled from two separate things: the soup (the broth, often loosened with a little fat) and the tare, a concentrated seasoning base that carries most of the salt and flavour. The classic move is to portion the tare into each bowl first, then pour the hot soup over it at roughly nine parts soup to one part tare, so you can keep the broth unseasoned and adjust each bowl. A standard bowl holds about 420 ml of soup and 120 g of fresh noodles; richer styles like tonkotsu or miso carry a touch more of both. Scaling is linear, so multiplying by the number of bowls gives your batch.
Worked example
Four standard bowls: 420 ml soup each = 1.68 L of soup, seasoned with about 47 ml of tare per bowl (roughly 187 ml total), and 120 g of noodles per bowl for 480 g in all.
Frequently asked questions
What exactly is tare?
Tare is the concentrated seasoning base — often a soy (shoyu), salt (shio) or miso blend — that sits in the bottom of the bowl. The unseasoned soup is poured over it, so the tare sets the saltiness of each bowl.
What ratio of tare to soup should I use?
Around one part tare to nine parts soup is a good starting point. Because you season bowl by bowl, you can taste and adjust rather than salting the whole pot.
How much noodle per bowl?
About 120 g of fresh noodles for a standard bowl, or 130 g for a rich, hearty style. Dried noodles weigh less for the same cooked volume, so use roughly 90–100 g dried.
