How to Choose the Right Coffee Cup for Your Business

Selecting cup sizes is just one piece of the puzzle. The style and material of your cups can affect heat retention, drink quality, and customer experience. Here are key factors to consider when sourcing hot coffee cups for your business.

Custom Branding

Custom-printed cups are one of the most effective ways to promote your brand. A well-designed logo on a cup can increase brand recognition and make your business appear more professional and trustworthy. Consider branded sleeves if you're working with stock cups but still want a personal touch.

Eco-Friendly Options

More consumers are paying attention to the environmental impact of disposable products. Compostable cups, recyclable liners, and plastic-free lids can all help reduce your footprint. If your business promotes sustainability, don't overlook the messaging power of eco-friendly cup choices.

Single vs Double Wall

Single-wall cups are more cost-effective but require sleeves for hot drinks. Double-wall cups provide built-in insulation, making them ideal for takeout-focused businesses and enhancing customer comfort. For higher-end service or to-go models, double-wall is usually worth the investment.

Poly vs PLA Lining

Poly-lined cups are traditional and moisture-resistant but not compostable. PLA-lined cups (made from plant-based material) are compostable in commercial settings and align with sustainable values. If eco-credibility is part of your brand, PLA-lined cups are worth the extra cost.

Squat vs Tall Cups

While some customers like the aesthetic of a taller cup, squat cups offer more stability and can be easier to carry, making them ideal for lobbies, break rooms, and room service applications. Consider how customers will use the cup, especially in grab-and-go settings.

Offering a range of coffee cup sizes helps you cater to a wider customer base while maintaining portion control and cost efficiency. For most businesses, sticking with the 8 oz., 12 oz., and 16 oz. sizes will meet the majority of your needs. From there, consider how construction, lining, and branding can elevate the coffee experience and enhance your reputation.
