The Space Bar: What It Does and How to Press It
The space bar is the long key at the bottom of the keyboard. Pressing it adds a blank space, which is how we separate one word from the next.

Tap the space bar with your thumb and keep your other fingers home. Quick taps, not big thumps!
Where is the Space bar?
The highlighted key is the Space bar on a typical Windows laptop keyboard. Keyboards vary a little by brand.
What the Space bar does
Without spaces,everythingwouldlooklikethis! The space bar is the biggest key because it gets pressed more than any other key. In normal English writing, about one character in every five or six is a space.
The space bar does more than make gaps between words:
- On a web page, it scrolls down one screen. Shift + Space scrolls back up.
- On many video players it pauses and plays.
- It checks or unchecks a box and presses a button that is selected.
- In lots of games it makes your character jump.

Which finger presses it?
Use your thumb. Most typists use the thumb of whichever hand did not type the last letter, but either thumb is fine. Keep your other fingers resting on the home row while you tap.
Fun fact
On old typewriters the space bar did not type anything at all. It just moved the paper one step to the left so the next letter landed in a new spot.
