One of the easiest examples to visualize is a 9-inches dinner plate. Put the plate bottom side down on a table and measure across the center from one edge to the other. In this case the measured distance is 9 inches, which exactly corresponds to a completed 9-inch plate.
2. Short Side of A4 Paper

A4 takes 8.27 inches on its short side, so this is less than 9 inches. It is easy to see the difference when holding an A4 sheet next to a ruler. Adding about three-quarter of an inch gives you a nice approximation of 9.

8. Small Rolling Pin

The compact rolling pin is 9 inches long. The rolling pin is also a delicious way to compare sizes in the kitchen since its straight length makes measurement especially clear, while there are rice bowls or cake tins that would be more difficult to quantify; A 9-inch rolling pin has both a comparison of height.

The decorative tiles are made in the size of 9 by 9 inches. This size of tile is particularly suitable for visualization, since both the width and height can represent 9 inches.
10. Handheld Clipboard

Mini clipboards measure about 9 inches long depending on the design. They are another beneficial work or school comparison.
11. Nine-Inch Ruler Segment

For example, a common twelve inch ruler has an obvious nine inch mark on it. So just pinpoint the zero point and proceed on to the mark where 9 is found. The length from there to the end of the ruler measures exactly three inches.
12. Large Pencil Case

Well, the pencil cases are 9 inches. They are rectangular so the length can directly be compared with a ruler or measuring tape.
13. Small Cutting Board

A compact cutting board can have one item about 9 inches long. This is most clearly illustrated with a square board, each side 9 inches long.
14. Tablet or E-Reader Cover

Some covers for smaller tablets or e-readers may even be less than 9 inches across. The specific measurement differs with the device and case design, so you should always refer to the dimensions of the manufacturer whenever precision is key.
15. Long Hairbrush

Some normal size brushes are around 9 inches from the bottom of your handle to the other side of the brush head. This makes a hairbrush yet another easy household comparison.
