30 oz Tumbler: Sizes, Handles and Lids Compared
A 30 oz tumbler is the size between an everyday cup and a 40 oz giant: enough water for a working day, still light enough to carry by hand. Here is what it holds, how big it is, which styles exist and what to check before ordering.
By Feng, Head of After-Sales Service & Online Marketing Lead
A 30 oz tumbler holds 30 US fluid ounces, which is 887 ml or three and three-quarter US cups, and most product pages round it to 900 ml. It suits buyers who want a day's water or a large iced drink without the weight and height of a 40 oz cup. The common styles are a straw tumbler with a large handle, a rounded straw tumbler without a handle, a tumbler with a folding ring handle on the lid, and a tumbler with interchangeable lids. BG Drinkware's 30 oz models stand about 20–26 cm tall with the lid on, and the two with listed weights come in at 370 g and 385 g. BG Drinkware, a drinkware manufacturer in Yongkang, China, makes 30 oz tumblers, most with a 304 stainless steel interior, several sold alongside a 20 oz version of the same body. Custom orders start at 500 pieces per colour, and a sample of an existing model takes up to 7 days.
How much does a 30 oz tumbler hold?
A 30 oz tumbler holds 30 US fluid ounces, or 887 ml. One US cup is 8 fluid ounces, so it holds three and three-quarter cups. Product pages usually call it 900 ml, and BG Drinkware's pages list it as 30 oz / 900 ml, so the two numbers describe the same size.
That is the full capacity to the brim. With the lid fitted and room left for a straw, the cup holds a little less in daily use. If your listing or packaging states a fill volume, agree how it is measured on the sample.
For the smaller size, see 20 oz tumblers; for the larger one, see 40 oz tumblers.
How big is a 30 oz tumbler?
A 30 oz tumbler is taller than a 20 oz cup rather than much wider. BG Drinkware's 30 oz models stand about 20–26 cm tall with the lid, with a base of about 7.2 cm, so most still taper to fit common vehicle cup holders. The handle and lid style change the height more than the capacity does.
| Model | Size with lid | Mouth / base | Weight with lid |
|---|---|---|---|
| Tumbler with steel handle | 20.3 cm high | 10 cm / 7.2 cm | 385 g |
| Covered-spout tumbler with handle | 9 × 13.4 × 25.8 cm | — | 370 g |
| Tumbler with folding ring handle | 9.3 × 24.5 cm (listed) | — | — |
| Tumbler with lid options | — | — / 7.2 cm | — |
For freight, the covered-spout tumbler packs 50 to a carton of 71 × 49 × 56 cm at 24 kg gross, and the steel-handle tumbler packs 25 to a carton at 12 kg. Ask for the carton details of the exact model before you book space.
Which 30 oz tumbler style should you choose?
Choose the style by how the cup is carried. A large side handle suits carrying by hand and a car journey, a folding ring handle on the lid suits hanging from a finger or a bag, a rounded body without a handle suits a clean retail look, and a lid-options tumbler suits buyers who want to choose the lid.
| Model | Lid and handle | Also available |
|---|---|---|
| Tumbler with handle | Dual-drink lid, straw, large open handle | 20 oz / 600 ml |
| Rounded straw tumbler | Dual-drink lid, no handle | 20 oz / 600 ml |
| Covered-spout tumbler | Covered straw spout, wide handle | 20 oz |
| Tumbler with steel handle | Integrated steel handle, clear sliding lid supplied | 600 ml |
| Folding ring handle tumbler | Transparent lid with spout and folding ring handle | — |
| Carry-handle tumbler | Dual-drink lid, carry handle, gradient finish | — |
| Tumbler with lid options | Choice of compatible lids, optional steel straw | — |
A straw lid or a sliding lid is made for drinking, not for carrying on its side. If the tumbler must survive a bag, specify a sealing lid and test it closed on the sample. For lid parts, see how to check a tumbler lid, seal and straw, and for handle choices see how to choose a tumbler handle.
Is a 30 oz tumbler better than a 20 oz or 40 oz one?
It depends on the buyer. A 20 oz cup suits coffee and desks, a 30 oz cup suits water for a working day, and a 40 oz cup suits buyers who want to refill least. For a first range, a 20 oz and a 30 oz on the same body make a common pair.
| Size | Holds | US cups | Typical use |
|---|---|---|---|
| 20 oz | 591 ml (sold as 600 ml) | 2.5 | Coffee, desk, car cup holder |
| 30 oz | 887 ml (sold as 900 ml) | 3.75 | Water for a work day, gym, iced drinks |
| 40 oz | 1,183 ml (sold as 1,200 ml) | 5 | Fewest refills |
Scaling one design across sizes still needs a check on each body, because the print area changes with the height and the taper. See where to place a logo on a tumbler.
How can a 30 oz tumbler be decorated?
On a coloured coated body, finished artwork is mostly UV printed, and a laser can engrave through the coating to show the steel. A bare stainless steel body takes screen printing or laser engraving, not UV printing. Gradient and other special finishes are agreed on the sample before bulk.
Laser results depend on the coating, the laser power and the machine, so approve a marked sample before bulk; see laser engravable tumblers. For printed logos that last, see why printed logos rub off.
What should you send to quote a 30 oz tumbler?
Send the capacity, quantity, model, colour, logo method, packaging, payment terms and trade terms. For a 30 oz tumbler, also say whether the lid must seal for carrying in a bag, and whether the cup must fit a car cup holder, because both change which model and lid suit the order.
Colours are matched to a Pantone code or a physical colour sample and confirmed on the sample. BG Drinkware's 30 oz models start at 500 pieces per colour, and the minimum is negotiable; the covered-spout and steel-handle tumblers count per capacity and per colour. A sample of an existing model takes up to 7 days, and bulk production takes 7–12 days after approval.
Every vacuum tumbler is temperature-tested unit by unit before shipping, and heat retention is checked on samples with 95°C water measured after 6 hours, or by the buyer's own method. For the range, see custom tumblers.

30 oz tumbler FAQ
Short answers to the questions buyers ask most about 30 oz tumblers: how much they hold, how they compare with 20 oz and 40 oz cups, whether they fit a cup holder and the minimum order. Where an answer names BG Drinkware, it uses the details on its product pages.
How many ml is a 30 oz tumbler?
A 30 oz tumbler holds 887 ml, because one US fluid ounce is about 29.6 ml. Product pages usually round it to 900 ml. That is the brim-full capacity, so the cup holds a little less once the lid is on and a straw is in place.
How many cups is a 30 oz tumbler?
A 30 oz tumbler holds three and three-quarter US cups, because one US cup is 8 fluid ounces. In 250 ml metric cups, used in recipes in Australia, Canada and New Zealand, it holds about three and a half cups.
Does a 30 oz tumbler fit in a cup holder?
Many do. BG Drinkware's 30 oz tumblers with a steel handle or lid options have a 7.2 cm base, and several models taper to fit common vehicle cup holders. Holders vary by car, and a large handle can catch on the console, so check the fit on the sample.
