What size is my space bar?

Is this spacebar 5.25 or 5.5? or anything else
The space bar is 10.5 cm long and the keyboard is the "g.skill km780"

I don't know if this is how you measure key caps but I found something on google referring to longer keycaps as 1.5 ect. Basically a regular square key like "w" would be 1 and if your enter key is 2.25 as long as "w" then the enter key would be 2.25. I need help distinguishing how long exactly my space bar is in these measurements.

I've been looking for space bar keycaps online but most of them are 6 or higher so because mine is shorter i'll commission one but that means I need the space bar size and I don't want to get it wrong which is why I've come to you guys to help me. Thanks!

according to my observation, your spacebar size is 5.5 (or 5.5u)
the bottom row of that board is: 1.5, 1.5, 1.5, 5.5, 1.25, 1.25, 1.25, 1.25

Looks like it is 0.75 below C and 0.75 below comma. 1.75*2 + 4 = 5.5 units.
Also, counting the width of the main section of the keyboard and subtracting the sizes of the modifiers keys on the bottom row: 13 + 2u Backspace, 3×1.5 mods on left,  4×1.25 mods on right. (13+2) - (1.5×3 + 1.25×4) = 5.5.
(The key unit is called "unit" or "1×1-key unit" because nobody has come up with a better name ... :-þ )

Yes, that is a very unusual space bar size. I'm sorry but I don't think you will find that as a single.
Your best chance would be to get a broken keyboard for cheap that has the same-sized key but even then it is not sure that the stabiliser mounts underneath are the same.

it's not the size that matters

It does if you are trying to fit it on your keyboard.
