On an average sized product, the minimum font size for ingredients should be set at 1.6mm based on a lower case “o” or an upper case “O”. This means your ingredient list will take less room if you choose to use upper case letters (capitals) — When given the choice, designers will usually select the option that will make the design look less crowded; This is the reason ingredient lists are usually capitalized.
