Various sizes are made (sizes as of 2008): miniature bars called "Fun Size" (19.7 g) and "Snack Time" (36.5 g) (both sold in multiple packs); a larger multi-pack size of 54 g; the regular sized single 58 g bar and a "king-size" 84 g bar which has since been replaced by "Mars Duo" (85 g) – a pack that contains 2 smaller bars of 42.5 g each instead of 1 large one. The regular 58 g single bar contains 260 calories.
