Create makeshift rulers using miscellaneous objects. Start by looking for random objects around the house, starting in the garage. In your wallet, you have dollar bills that are close in size to rulers. The average bill is at least half a foot and easy to fold into the pocket, so it is the ideal choice.

Another important item to use is a credit card along with a cell phone. Write down the measurement of each object and save each one as a makeshift ruler.

First, know the different types of measurements that are commonly used. From the smallest to the largest, there are millimeters, centimeters, inches and feet. Think of the general lengths for each type of measurement. Then, think of objects you own that are equivalent to these lengths.

For instance, the average pen is the equivalent of nearly five inches, which is nearly half a foot. In total, a foot is twelve inches or one third of a yard. You want to list all of the common items that equal the length of a foot. Also, look for items that equal the length of a yard if you need to make a longer measurement.

You will find it easier to use items that already exist instead of creating your own. It takes too much time to create a ruler out of paper and pencil marks. The main point is to use items that are already lying around for your convenience.
