French Press Size Guide: 350ml vs 600ml vs 1000ml and How Many Cups You Get

The 350ml Trap: Why You Get Less Coffee Than Expected

A 350ml French press does not give you 350ml of coffee. The 350ml on the box is how much the glass holds. You do not fill it to the brim, and the wet coffee grounds soak up some of the water. So you pour out less coffee than the size on the box. For a 350ml press, plan on about one mug. Many buyers do not know this before they buy.

This is not a flaw. Every French press works this way. One coffee roaster's French press guide fills the press "to just below the bottom of the pouring spout." It then waits a minute, "allowing the coffee to absorb the water" (Sightglass Coffee). How much you lose depends on how much coffee you use. Keep this in mind when you pick a size.

Size fact: One US cup is 240 ml, says the US National Institute of Standards and Technology (NIST cooking measurement equivalencies). But the word "cup" on many French press boxes means a much smaller cup, about 120 to 125 ml. The Bodum Chambord, for example, is sold as a 3-cup press at 0.35 litre and an 8-cup press at 1 litre (Bodum Chambord size list). So a "3-cup" French press makes about one real mug of coffee.

How Many Cups Is 600 ml, 350 ml or 1000 ml?

A "cup" is a kitchen unit of volume, and one US cup is 240 ml. So 600 ml is 2.5 US cups, 350 ml is about 1.5 US cups, and 1000 ml is about 4 US cups. On a French press box, where one "cup" is about 120 ml, 600 ml counts as about 5 cups.

The table shows each French press size in the units people search for. The US cup numbers use the NIST value of 240 ml for one cup. NIST also gives one cup as 0.24 litre (NIST approximate conversions).

These numbers are the size of the glass, not the coffee you pour. Wet grounds keep some water back, so you get a little less in your mugs.

600 ml kitna hota hai?

600 ml kitna hota hai? 600 ml = 0.6 litre, yaani aadhe litre se thoda zyada. In English: 600 ml is 0.6 litre, a little more than half a litre. That is 2.5 US cups, or about 2 big mugs of 250 ml each with a little left over.

What about a 250 ml French press?

A 250 ml French press would hold about one US cup of 240 ml, or about 2 French press cups. That is enough for one small cup of coffee. Our smallest glass French press is 350 ml. For coffee on the go, our French press travel mug holds 400 ml.

How much coffee for a 350 ml French press?

For a 350 ml French press, use about 22 to 35 grams of coarse coffee. That comes from the US National Coffee Association (NCA) ratio for French press: "1 gram of coffee to 10–16 grams of water (1:10 to 1:16)" (NCA, About Coffee). One ml of water weighs about one gram, so you can use ml. By the same ratio, a 600 ml press takes about 38 to 60 grams, and a 1000 ml press about 63 to 100 grams. For a full grams chart, see our French press coffee ratio guide.

Cups and Mugs Per French Press Size

A 350ml French press fills about 1 mug, a 600ml press about 2 mugs, and a 1000ml press about 3 to 4 mugs. The table shows the cup label and mug count for each size. The coffee you pour is our rough estimate, not a lab test. Your number depends on how much coffee you use and how full you fill the press.

Which Size Fits Your Household?

The right French press size depends on how many people drink coffee and how many cups each person wants. Solo drinkers need at least 350ml. Couples should get 600ml. Families or anyone who hosts guests should get 1000ml.

Prices in this table are from our store on 12 October 2026, and every size above was in stock that day. The Aero glass French press comes in Clear, Black and Copper, and the price changes a little by colour. The travel mug also comes in Navy Blue at Rs 1,499.

Mug Size Math: French Press Cups vs Real Mugs

Many French press makers count one "cup" as about 120 to 125 ml. That is about half a US cup, since NIST lists 120 ml as 1/2 cup. Mugs are bigger, and they vary a lot from home to home. So an "8-cup" French press of 1 litre fills only about 3 to 4 real mugs. To know your own mug size, fill it once from a measuring jug.

Here is the simple rule: divide the cup number on the box by 2 to get mugs of 250 ml. Then expect a little less, because the grounds keep some water. An "8-cup" press makes about 3 to 4 real mugs. A "3-cup" press makes about 1 real mug.

My Sizing Recommendation

If you can only buy one French press, get the 600ml. It is the most flexible size. It makes 2 good mugs — enough for a couple, or one person who wants a refill. It is not too big to waste coffee if you brew for yourself, and not too small to share.

The US National Coffee Association says the press should fit the batch: "For the best coffee, it’s better to match the size to the batch—you lose quality trying to make a small batch in a larger device" (NCA French press guide). So buy the size you will fill on most days.

If you drink coffee alone and want the freshest cup, 350ml is fine. But know that you get about one mug. No refill. No sharing.

The 1000ml is for families, hosts, and coffee lovers who want to make a big batch of cold brew. The NCA gives a cold brew ratio of "1 gram of coffee to 4-5 grams of water (1:4 to 1:5)" and about 12 hours of steeping (NCA cold brew guide). That much coffee takes up a lot of room, so a bigger press gives you a more useful batch. For the full method, see our French press cold brew guide.
