About 40 soda crackers, often known as saltines, are contained in one sleeve, though the exact amount varies slightly depending on the brand. Each serving of saltines contains roughly 70 calories, or 5 crackers.

A serving size of soda crackers weighs 16 grammes. These crackers have no fibre, 150 milligrammes of salt, and about 1.5 grammes of fat. The nutritional value of saltines is only fair when compared to crackers made with whole grains, and there is little difference between popular brands and store brands. They all have a light flavour that is salty and resembles flour. Store brands are roughly 6 cents less expensive per serving than name brands, which cost about 10 cents.
