1. 16-Inch Laptop Screen (Diagonal)
A 16-inch laptop screen measures 16 inches diagonally, corner to corner. This size has become very popular for work and study, because the screen is large enough for two windows side by side, while the laptop still fits in a backpack.
If you have used a large laptop, its screen diagonal is your reference. Remember, the number is always the diagonal, not the width.
2. 16-Inch Portable Monitor (Diagonal)
A portable monitor sold as 16 inches also measures 16 inches diagonally. These monitors are made to travel with a laptop, so they are thin, light, and close to the size of a laptop screen.
Place a portable monitor next to your laptop and the two screens look almost the same size. That diagonal is 16 inches.
Kitchen & Food
3. Large Pizza
A large pizza is usually 14 to 16 inches in diameter, and many restaurants sell a 16-inch large pizza. That measurement is straight across the pizza, crust to crust.
A large pizza that feeds three to four people is often 16 inches across. It is bigger than a foot by a full 4 inches, which you can see at a glance on the table.
4. Large Frying Pan
An extra-large frying pan can reach 16 inches in diameter, though most home pans are 12 to 14 inches. A 16-inch pan is a commercial or family-size pan, made for cooking large meals.
If a pan looks much wider than a dinner plate, and it covers a large burner completely, it may be close to 16 inches across.
5. Serving Tray
A large rectangular serving tray is often about 16 inches long on its long side. It is made to carry several cups, plates, or dishes at once, so it needs that extra length.
Carry a tray with two hands, and the long side running left to right is often about 16 inches. It is a practical kitchen reference.

6. Throw Pillow
A standard square throw pillow is commonly 16 by 16 inches, and many sofa pillows are sold at exactly this size. It is a little larger than a 14-inch cushion, and it fills an armchair nicely.
Hug a sofa pillow to your chest: if it covers most of your chest, it is probably around 16 inches square.
7. Wall Clock
A large round wall clock is often 16 inches in diameter. This size is popular for living rooms and offices, because it can be read from across the room.
A clock that looks clearly larger than a dinner plate, but smaller than a pizza, is often about 16 inches across.
8. Level Tool
A standard spirit level for home use is often 12, 24, or 48 inches, but many torpedo levels and shorter levels are sold at 16 inches. A 16-inch level is handy for shelves, pictures, and small carpentry jobs.
Hold a level against a shelf: if it is a compact, one-hand tool a little longer than a ruler, it may be 16 inches long.

9. Kids Bike Wheel
A kids bike with 16-inch wheels has wheels that measure 16 inches in diameter, from one side of the tyre to the other through the centre. This is a standard size for children aged about 4 to 6 years.
The number in a kids bike name is the wheel size. A “16-inch bike” means its wheels are 16 inches across, which is a perfect, exact reference.
10. Bowling Ball Bag (Width)
A single-ball bowling bag is usually about 16 inches wide, made to hold one bowling ball plus shoes and a small towel. The bag’s width matches the ball it carries, with room around it.

11. Small Toolbox
A small home toolbox is often about 16 inches long, made to hold a hammer, screwdrivers, pliers, and a few other basic tools. Larger toolboxes can reach 20 inches or more, but the compact home size is close to 16.
Open a toolbox in a home cupboard and measure it end to end: if it is a small, one-handle box, it is very often around 16 inches long.
12. Chainsaw Bar
A chainsaw bar is measured in inches, and 16 inches is one of the most common homeowner sizes. The measurement runs from where the bar leaves the saw body to its rounded tip.
