The Severin AT 2515 is a long slot toaster, which means that it only has one slot, but this slot is long and wide enough to accommodate larger slices of bread or even baguette slices.

- The slot is 38 cm long and 12.5 cm wide, which is enough to toast two large slices of bread.
- The depth of the slot is also sufficient to ensure complete toasting, as the toaster is equipped with toasting time electronics and adjustable browning level to brown the bread slices evenly on both sides.
