Most cup-buying questions start with the same problem: which size? Pint, half-pint, two pint, stackable, rigid, stadium-style. The categories blur together quickly when you're staring at a quote spreadsheet, and the wrong choice locks you into a format that doesn't suit how your bar actually runs.
We make all of these formats out of our facility in Stockton-on-Tees. Over the past three years we've shipped more than ten million of them. So this is a straight answer to which size goes where, written from the factory floor rather than a marketing brochure.
Short version: there's no universally "best" size. The right cup depends on how your guests drink, how your bar staff serve, and how your venue stores cups between sessions.
Pint festival cups: when a full pint is the right call
The pint is the default for a reason. It matches how most UK festival audiences drink, it lines up with bar pricing, and it cuts the number of trips a guest has to make to the bar in half compared to a half pint serve.
We make pints in two formats. Pint to line is 568ml, with the legal pint mark filling to a printed line, leaving room for a head. UKCA marked, CE compliant, the right call for licensed bar service of draught beer. Pint to brim is 625ml, which fills right to the top with no head allowance. That format suits soft drinks, cocktails and mixed serves where there's no head to account for.
Buyers regularly conflate the two. They are not the same cup. If your bar is pulling beer with a head, you want pint to line. If you're serving cocktails or sodas, pint to brim works better because you're using the full volume.
For bigger formats, our pint festival cups range goes up to two pints (approximately 1,100ml, UKCA marked at the two pint measure with an integrated handle for one-handed carrying). Two pint cups suit headline-act bars where queue spikes are predictable. One trip to the bar buys two pints, halving the throughput pressure.
Half-pint cups: the case for smaller serves
Half pints are 330ml at the measure line, UKCA marked at the half pint, manufactured to the same rigid food-safe polypropylene specification as our pint range. They are not, despite assumption, a downgrade.
Half pints earn their place at spirit bars, cocktail vendors, and soft drink stalls. They work for cider measures, water serves at endurance events, and any vendor where a pint isn't the natural unit. They also suit licensed concourses where serving rules limit volume per transaction.
What we tell venue managers: don't run your headline draught bar on half pints. The throughput maths doesn't work, and queues will balloon. Use half pints as a secondary line for specific bars where the format matches the serve. For everything else, the half-pint festival cups page covers the full range.
Stackable vs rigid cups: storage, logistics, and venue fit
This is where most buyers underweight the decision. A standard rigid cup nests but doesn't lock together. A stackable Stack Cup format has a moulded shoulder that locks each cup to the next, which compresses storage volume significantly and stops cups slipping during transport.
Why does that matter? Pallet space at a festival site is finite. Bar staff loading shelves at a busy venue lose time digging through loose stacks. Stackable cups solve both. We make Stack Cup formats in pint to line, pint to brim and half pint, plus stackable wine and Stack Flute champagne formats.
Honestly, for events of any scale, stackable is the sensible default unless you have a specific reason to pick a non-stack format. The unit cost difference is small. The logistics saving is not.
Rigid non-stack cups still have their place. Hot drinks cups, certain branded designs where the shape of the cup wall matters, single-event runs where storage and re-deployment isn't a factor.
Stadium and arena cups: what makes them different
Stadium environments have a specific operational profile. High throughput in compressed time windows. Multi-season cup lifespans where cups are washed and re-issued for the next fixture. Deposit schemes that depend on cups surviving heavy guest use over months and years.
That points in two directions for cup choice. First, the print method. Full colour IML (in-mould labelling) is fused into the cup wall during manufacturing, which means it won't peel, flake or fade even after hundreds of commercial dishwasher cycles. For a stadium cup that's going to be cleaned hundreds of times across a season, IML pays for itself. Surface print works for one-off events. IML works for multi-season programmes.
Second, format. Stadium concourses where bar visits compete with kick-off times benefit from larger formats like pint or two pint, because each transaction serves more volume and reduces the number of trips per guest. Half pints suit hospitality boxes and licensed-volume restrictions, but the main bowl bars usually want pints.
How to choose the right cup size for your event
Three factors. Start with the serve. What's actually in the cup? Beer with a head means pint to line. Cocktails, soft drinks or wine means pint to brim or half pint depending on volume. Spirit measures and cider means half pint. Match the cup to the serve, not the other way around.
Then bar throughput. How many guests, how many bars, how compressed is the peak hour? More guests per bar plus shorter peak windows pushes you toward larger formats, like pints or two pints, because each transaction serves more volume.
Finally storage and logistics. Stackable cups save pallet space and bar staff time. For anything over a few thousand cups, default to stack formats unless you have a specific reason to pick a non-stack design.
The mistake we see most often is buyers picking by aesthetic before serve. The cup looks right in the proof, the print sits well, and the format gets locked in before anyone asks whether the bar can actually run on it. Pick the format first. Pick the print after.
There's no single right answer to festival cup sizing, but the right answer for your event is usually obvious once you've thought through serve, throughput and storage in that order.
