Although it may seem abstract, 4 inches is a common measurement used to compare the lengths of items or get an idea of how long or tall something is.
However, thinking about some everyday items that are almost or exactly 4 inches long can help you better visualize the length.
1. A Credit Card
Credit or other bank cards are an excellent way to quickly get an accurate measurement of something because they’re a universal size.
A standard credit card is 3.5 inches long, which is only half an inch shorter than 4 inches.
This means that visualizing a credit card or holding one up to an object can give you a very good idea of what nearly 4 inches looks like.
You can also use credit, bank, or business cards to measure or estimate 4 inches by looking at the height of the cards.
Most standard credit and business cards are 2 inches tall, so you only need to picture two cards together to accurately estimate 4 inches.
2. Four Small Paper Clips
Paper clips can be found easily around the home or office, and they’re a standard length, so visualizing paper clips or lining a few up end-to-end can make it easy to estimate something’s length with relative accuracy.
Small paper clips are exactly 1 inch long, so picturing or using four small paper clips can help you estimate 4 inches.
Large paper clips, on the other hand, are about 2 inches long, so you would only need to line up two of these clips to get an idea of what 4 inches looks like.
3. A Toilet Paper Roll
A toilet paper roll might not seem like an ideal way to estimate length, but it’s a common item that anyone can easily visualize.
In fact, toilet paper rolls are all 3.7 inches long, which is very close to 4 inches.
Picturing the length of a toilet paper roll can help you easily estimate 4 inches.
4. A Popsicle Stick
Popsicle sticks are often used to estimate 4 inches because they are about 4.45 inches long.
Craft popsicle sticks may be slightly wider and longer than the popsicle sticks found in your favorite dessert, but visualizing either type can help you get a good feel for what 4 inches look like.
5. A Hand-Width
Using your own body to estimate measurements is useful and simple.
For example, the width of most adult’s hands across the palm is about 4 inches.
This does vary depending on the gender and size of the person, but it’s a great way to get a quick idea of how long or tall something is.
In addition, the length of most adult’s thumbs is about 1 inch.
You can place your thumb next to something to get a good idea of how long or tall it is.
6. Four Quarters
Coins must all be an exact size, and this makes them very useful for measuring things with accuracy.
You can use several different coins to measure things or get a feel for the size, but quarters are perhaps the easiest method because they must be exactly 1 inch in diameter.
Picturing four quarters, lined up, can help you picture 4 inches in length. Pennies, on the other hand, are about .75 inches across.
Picturing five pennies, lined up end to end, will help you visualize almost 4 inches in length.
7. A Business Envelope
Business envelopes are available in standard sizes, which makes them handy for estimating measurements.
A standard business envelope is 4 inches tall, so you only need to look at the side of an envelope to accurately measure that height.
You can also use the length of the envelope to measure.
Most business envelopes are 8 inches long, so simply picture half of an envelop to estimate what 4 inches look like.
8. Two Baseballs
Sports equipment is usually a standard size in order to keep things fair.
Baseballs, for example, have a diameter of 2 inches.
This means that picturing or holding two baseballs together can help you accurately estimate what 4 inches look like.
9. Two golf tees
You can also picture a couple of golf tees to help you estimate 4 inches.
Most golf tees are about 2 inches tall, so picture two tees together to estimate 4 inches.
