14 Things That Measure Around 11 Inches

A Sheet of Letter-Size Printer Paper
A standard sheet of US letter paper is 8.5 by 11 inches. That makes the long side exactly 11 inches. It is the most exact everyday reference on this list. Hold a sheet upright and you are holding 11 inches in your hands. Printers also list paper sizes in millimeters, but the inch version is the one to remember here.
An American Football
An official NFL football is exactly 11 inches long from tip to tip. The league keeps this number strict so every ball flies the same way. College and high school balls are a touch shorter. Next time you watch a game, remember that the ball in play is a perfect 11-inch reference.
A Rugby Ball
A full-size rugby ball is 11 to 11.8 inches long. That is the official size 5 used in adult matches around the world. It looks like an American football but with rounder ends and no laces. If rugby is your sport, you already know this length by feel.
An 11-Inch iPad
Tablets are sold by screen size, measured corner to corner on the diagonal. Apple sells 11-inch iPad models, so the screen is exactly 11 inches across. Many Android tablets come in the same size. Smaller tablets sit closer to 8 inches, so the jump to 11 is easy to feel in your hands.
An 11.6-Inch Laptop
Small laptops and Chromebooks often have 11.6-inch screens. That is just over half an inch more than 11 inches. These little machines are popular with students and travelers. If you own one, the screen diagonal is a handy 11-inch guide you carry every day.
A Standard Dinner Plate
Dinner plates usually run 10 to 12 inches across. The most common home size is 10.5 inches, and many restaurant plates are a full 11 inches wide. That makes a restaurant plate a near-perfect circle of 11 inches. Luncheon plates are smaller, closer to 9 inches, so check the size before you guess.
A Men's Size 10 Shoe
A US men's size 10 shoe fits a foot about 10.7 inches long, and the shoe itself runs close to 11 inches heel to toe. Shoe sizes grow in steady steps, so nearby sizes are close to this too. Look at your own shoes for a personal reference. Your feet carry a measuring tool with you everywhere you go.
An 11×14 Picture Frame
Picture frames are named by the photo they hold. An 11×14 frame holds a photo that is 11 inches on the short side. That makes it a clean 11-inch reference you can hang on a wall. A 5×7 frame is much smaller, so the difference is easy to see side by side.
A Standard Paper Towel Roll
Paper towel sheets are 11 inches wide, so a standard roll stands about 11 inches tall. Every brand keeps this width steady so rolls fit standard holders. It is a handy reference because nearly every kitchen has one. Next time you grab a sheet, take a second look at the roll.
A Folding Umbrella
A standard folding umbrella closes down to about 10 to 11 inches long. That is why it fits so neatly in a bag or a car door pocket. The tiniest pocket models fold even smaller, down near 6 inches. For the classic travel size, though, 11 inches is the number to remember.
A Standard Stair Tread
The flat part of a stair step is called the tread. Building codes set it at 10 to 11 inches deep for safe footing. Walk up any staircase and each step you climb is about 11 inches front to back. It is a reference you use every single day without thinking about it.
