How do you measure volume in a KeepCup?

To brim full, with the lid on. Our barista-standard cups were designed to replicate single-use takeaway cup volumes, which are described in fluid ounces, so a 12oz KeepCup holds what a 12oz takeaway cup holds.

  • Press-on lids (Original, Brew): Volume measured brim full. Designed to drink lid on or off, and to allow latte art and a clean pour.
  • Press-in lids (Cold Cup): Slightly reduce internal volume, because the lid sits inside the rim.
  • Screw-fit lids (Commuter): Also adjust internal volume a little, in exchange for a leakproof seal.

The principle is the same across the range: match the café pour so a barista can fill it without guesswork, and make it an easy fill you enjoy using.

What drinks are best for a 12oz KeepCup?

A 12oz KeepCup (around 340ml) is the most popular size, often equivalent to a “medium” takeaway coffee at cafés. It offers a balance between volume and portability, making it versatile for a wide range of drinks.

Specialty Coffee: Perfect for lattes, cappuccinos, and flat whites if you like a little extra milk. It’s also a great choice for larger long blacks or Americanos when you want a longer coffee without it being too diluted.

Specialty drinks: Works well for chai lattes, matcha lattes, mochas, and hot chocolates where the extra room balances flavour and milk.

Cold drinks: Ideal for iced lattes, iced long blacks, cold brew, and even small smoothies or juices.

Tea: Generous enough for a full black tea, green tea, or herbal infusion, especially if you enjoy a larger cup to sip on throughout the morning.

Batter up! the 12oz KeepCup is the “all-rounder” — great if you like a medium-size coffee, want extra room for milk-based drinks, and want versatility for hot and cold beverages.

What is a 12oz reusable coffee cup best for?

A 12oz KeepCup is the all-rounder, and our most popular size. It is the café standard for a regular latte, cappuccino, chai, matcha or hot chocolate, and works just as well for iced drinks.

  • Materials: Tempered glass, lightweight plastic or insulated stainless steel.
  • Lid: Press-on splashproof lid, so you can drink with it on or off.
  • Carry: Fits car cup holders, backpacks and shoulder bags.
  • Made in the UK: Australian-designed and assembled here since 2011, with bands and lids in a wide range of colours.

If you usually order a “regular”, this is your size. Build your own with Design Your Own Brew — pick size, material, band, lid and plug.
