Six inches is:
- Not too small to hold or grip

- Long enough to be functional
- Short enough to be portable
That balance is why so many everyday items are designed around this length.

That’s extremely close to 6 inches — close enough that most people cannot visually tell the difference.
Why it’s useful:
Most people have handled paper currency countless times. This makes it one of the easiest mental references for 6 inches.
3. A Typical Smartphone
