How to Measure Without a Ruler

The standard size of U.S. money makes it a suitable ruler in a pinch.

When you are working around the house or working on your latest craft project, you likely need some way to measure the pieces used in the project. If you can't find a ruler or tape measure, pull out your wallet. American money is all the same size, making cash a perfect substitute when you need a ruler.

Things You'll Need

• Dollar bill

Instructions

1. Place the dollar bill on a flat surface, like a table or counter. Run your hand flat across the bill, rubbing out any wrinkles.

2. Lift one end of the bill and move it over to the opposite end, folding the dollar in half. Carefully smooth down the crease and then unfold the bill.

3. Fold one end of the bill over until it meets the center crease. Repeat on the opposite end, creating a total of three creases in the bill.

4. Unfold the money and lay it against the object you are measuring. Count the number of creases the object passes. A dollar bill is 6 inches long, so each crease indicates 1.5 inches.

5. Place additional bills end to end for longer objects. Count the number of bills it takes to measure the object and multiply by 6 inches.

Tips & Warnings

• All American paper money is the same 6-inch length.
