Editing Backspace key (section)

==Layout==
Like most keys, the size of Backspace varies widely. The most common two sizes in modern keyboards are 1 [[unit]] and 2 unit. Modern [[ANSI]] and [[ISO]] keyboards typically use a 2 unit Backspace. Japanese keyboards widely use a 1 unit Backspace.

Older mechanical keyboards made in East Asia tended to have a [[return key|"Big-ass" Enter]] key and a 1 unit Backspace, for example the well-known [[Chicony KB-5181]]/5182. The small Backspace key makes room for one of the keys displaced by the size of the Enter key. The combination of big-ass enter and 2 unit Backspace exists, for example the [[Tulip ATK 030244]] and [[Monterey K104]]; in such cases, the displaced keys tend to be moved between the [[control key|Control]] and [[alt key|Alt]] keys.

Some vintage keyboards that have the Enter/Return key further to the right than the norm typically place the Backspace key at the same position as a 1 unit key but extend its size towards the right to 1.25 or 1.5 units. 
Examples from Japan of such non-standard sizes include the [[Sony NEWS NWP-411A]] and a [[Topre JDL]] keyboard. The [[Atari ST]] has a 1.5 unit backspace and 1 unit keys below it to the right of a [[Return key|Return]] that is ''not'' displaced further right than standard.
