Short domain names that are still available
On .com the short names are gone, and the table below says exactly how gone, length by length. Other extensions still have plenty left at the same lengths, which is the case for looking past .com.
For the size of each extension overall, and how fast it is growing, see how many domains are registered in each.

Share of each length still unregistered, as of . Hover a figure for how it was arrived at. .com and .net were asked of the registry name by name; the rest are counted from zone files, which is an estimate rather than a list, so those have no page of examples behind them.
Why the short ones went first
A length class is a fixed number of names and it never grows. Two letters is 676 of them, three is 17,576, four is 456,976 — small enough that a registrar, a speculator or a drop-catcher can hold the whole space in mind, and on .com they have. What separates the columns is demand rather than size: both extensions opened in 1985 and both hold the same 456,976 four-letter names, but one of them is where everybody looked first.
Real words are the exception to that, and they go first everywhere. We checked all 620 of them on .com and .net and not one was free.
