7-Eleven brewed coffee scales with size, and the big fountain sodas add up fast. 7-Eleven doesn't publish official caffeine figures, so these are estimates based on cup size and standard values. Some tests have found 7-Eleven coffee stronger than average, so treat these as a floor.
Coffee sizes: Small 12 oz · Medium 16 oz · Large 20 oz · XL 24 oz.
