How Many Ounces in a Pint?

When I work with customers from other countries or write product specifications for drinkware, I often get the same question: How many ounces are in a pint?
Knowing how to do this conversion is helpful not just for cooking, but also for comparing the sizes of drinkware, especially if you’re looking for custom bottles to sell, give as gifts, or use for marketing.

How Many Ounces in a Pint?

In the US, 1 pint is equal to 16 fluid ounces (fl oz).
Most food and drink packaging and applications use this standard measurement.

But if you work with clients in the UK or Europe, the number looks different because the UK uses the Imperial system.

• 1 US pint = 16 fl oz

• 1 UK pint = 20 fl oz

The US pint measurement (16 oz) is the most relevant standard for most people who buy drinkware, especially in the B2B market.

Why Drinkware Buyers Should Care About Pint-to-Ounce Conversion

When you choose or customize a water bottle, mug, or tumbler, knowing how many ounces fit in a pint can help you figure out how much it can hold. For instance:

• A 16 oz bottle holds exactly one US pint.

• A 32 oz sports bottle equals two pints.

• A 12 oz insulated cup is three-quarters of a pint.

When businesses buy custom drinkware for supermarkets, promotional agencies, or distributors, they need to know the exact volume so they can match the product features to what the market wants.

Comparing Pinto-Ounce Sizes with Diller Water Bottles

As a bottle manufacturer, I often help clients choose sizes that match their customers’ lifestyles. Here’s how pint conversions relate to some of the bottle sizes we commonly produce:

• A 16 oz / 480 ml bottle is ideal for daily hydration and matches the exact volume of one US pint.

• A 20 oz / 600 ml sports water bottle offers slightly more capacity, suitable for outdoor or fitness customers.

• A 32 oz / 1-liter bottle equals two pints, preferred by gym users or people who track water intake.

How to Picture a Pint When Picking Bottle Sizes

Here are some easy ways to compare what a pint looks like in real life:

• A standard soda bottle (500 ml) is close to one US pint.

• A typical medium-sized insulated tumbler is around one pint.

• Many of the custom bottles clients request for corporate gifting fall between 14–20 oz, overlapping closely with pint measurements.

These comparisons make it easier to figure out how much a bottle holds without using a conversion chart.

Which one should you use: a US pint or a UK pint?

If your business mainly sells to:

• North America → Use the US pint (16 oz)

• UK & some Commonwealth markets → Customers may expect 20 oz per pint as the standard beverage volume

For global brands and OEM clients, I usually recommend listing bottle sizes in:

• Ounces

• Milliliters

• Liters

This keeps things from getting mixed up in different markets.
