A Standard Dinner Knife

Most common stainless steel dinner knives measure 9 to 9.75 inches overall. It is the knife placed to the right of the plate in a typical table setting, the one used for cutting meat during the main course. It is a great real-world reference for visualizing 9–10 inches in length. The moment you are setting the table or eating out, grab the dinner knife; it is practically a 10-inch ruler.
iPad

There are tablets like the iPad 9th generation and 10th generation that support screens measuring approximately 10 inches. The 9th generation has a true 10.2-inch display, and the 10th generation comes with a 10.9-inch display. Even though it is not a perfect 10-inch tool since no iPad is exactly 10 inches, it is one of the most common household tech items for eyeballing about 10 inches without a ruler.
Bread Knife Blade

Bread knife blade, the cutting portion from heel to tip is an excellent everyday reference for approximately 10 inches. Many popular and high-quality models feature blades right around that length. The total knife length, including blade and handle, is usually 14-16 inches, but for measurement purposes, you have to take into account the blade portion only. This will be helpful as a 10-inch reference.
Three Credit Cards Lined Up

A credit card is yet another everyday item that can be used as a reference for 10 inches. It forms an accurate everyday reference. All you need to do is line up three credit cards along their longer edge, and you will get the 10-inch length. This is a quick ruler substitute since most people carry credit cards with them. It is a super convenient, no tools needed way to gauge 10 inches quickly.
Frying Pan

A frying pan is one of the most reliable and common household items. The standard frying pans are sized 10 inches or slightly over. Frying pans are measured across the top rim, not the flat cooking surface at the bottom. A frying pan typically has a rim diameter of about 10-10.5 inches, thereby making it a good 10-inch reference. If you have a standard 10-inch frying pan in your kitchen, it is an incredibly handy, no extra tool reference.

Standard Wall Clock

A wall clock is one of the most relatable everyday references for visualizing exactly 10 inches. The measurement refers to the diameter across the clock face, not including any outer frame. These clocks are super common in kitchens, offices, bedrooms, and classrooms. They are large enough to read from across a room but compact enough not to overwhelm small walls. Next time you see a basic round wall clock that’s not too big or small, chances are it is about 10 inches across, perfect for getting a quick mental picture of that length.
10-inch Photo Print

Popular standard sizes come in 8×10 inches. It is available in both portrait and landscape. Another photo print is available in 10×10 inches.

It is super common for professional prints. So, it can be said that a 10-inch photo print is a good reference for 10 10-inch measurement.
Men’s Size 9 Shoe (US)

A men’s US size 9 shoe is a great real-world reference for 10 inches, though the exact length varies slightly by brand and style. The outer sole length of the shoe itself is often 11–11.5 inches, but the inner length or Brannock device measurement for size 9 is commonly cited as 10.5 inches in many guides. This makes it surprisingly close to 10 inches for visualization. Next time, you are shopping or spot a pair, it is an easy way to picture roughly 10 inches.
Paperback Book Height

Many everyday novels, memoirs, or self-help books fall right around this range, making a typical paperback an easy mental benchmark. You pick up a standard novel off your shelf or at a store, flip it upright, and you likely have roughly 10 inches in your hand. So, it has come to the fore that a paperback book height is a solid everyday reference for visualizing 10 inches. Mostly larger trade paperback novels or non-fiction books come in this size.

A poker-sized playing card measures 2.5 inches wide × 3.5 inches tall. It is one of the common items most people have access to. Lining up three cards along their longer side, which is 3.5 inches each, gives exactly 10.5 inches total length.

Clipboard

A standard letter-size clipboard, which is the most common type for US offices, schools, nurses, coaches, etc., is a fantastic everyday reference for visualizing lengths around 9–10 inches.
