Ever wonder how long 4 inches actually is? I was trying to picture it the other day and realized most people just guess. Turns out it's about the width of your palm or a TV remote section - way shorter than you'd think. A credit card is like 3.4 inches, so 4 inches is just a tiny bit more. If you need a quick reference, it's roughly 10.16 centimeters or a little over half a dollar bill's length. Honestly, 4 inches sounds bigger in your head than it actually is when you see it in real life. Next time you're measuring something small, just remember your palm width - that's basically your 4 inches reference right there.
