How many ml is a flat white?

A standard flat white is 227ml, which is the 8oz cup most cafés pour into. A piccolo is roughly 100ml and a cortado around 120ml, so an 8oz reusable cup covers all three with headroom.

Will a small reusable cup fit a car cup holder?

Most 8oz reusable cups have a base diameter between 65mm and 75mm, which fits standard car cup holders. Larger 16oz cups and wide-base bottles often do not — check the base measurement rather than the capacity.

Do cafés charge less if you bring a reusable cup?

Many independent cafés offer a discount of roughly AU$0.50 per drink for bringing your own cup, and some chains run loyalty credits instead. At one coffee a day that discount alone covers a mid-priced reusable cup within a few months.

The best small (8oz) reusable coffee cup

What is the best small or takeaway reusable coffee cup?

For an 8oz flat white, piccolo or cortado the Fressko Bino 227ml is the pick — it matches the standard small café pour exactly, so baristas do not have to guess the volume, and it fits every car cup holder we tried.

Evidence227ml is the reference 8oz pour used by most Australian cafés; scored 88/100 with the same seal and materials construction as the Camino.

How we decided

Every product carries one 0–100 overall score built from the same six sub-scores: seal integrity, thermal performance, cleanability, materials safety, repairability and cost per year of ownership. Category-specific weightings are published on each product page.

The Reusable Edit is independent and takes no payment for coverage. Outbound retail links are affiliate-tracked; commissions never change a score or a ranking.
