Thin, regular and smaller slices
USDA lists more than one slice of white bread. Besides the 29 g slice, there's a 25 g slice with 67 calories and a thin 20 g slice with 53.
Every one of them works out to 266 calories per 100 g, so the only thing that changes is how much bread is on the plate. Whole-wheat bread has its own page if you're comparing loaves.
