3. A 27-Inch Wall Oven
Single wall ovens are sold in standard width categories, and 27 inches is one of the classic sizes. A 27-inch wall oven is made to fit a cabinet opening of that width in a fitted kitchen.

Large checked suitcases commonly measure about 27 inches tall, including the wheels and handle. This size is a favourite for longer trips, holding clothes for one person for a week or more with room to spare.
Suitcase sizes are listed by height more than any other dimension, which makes them easy to check. A large case standing by a check-in desk reaches roughly 27 inches high.

7. A Baritone Guitar Scale Length
A baritone guitar is a longer, deeper-sounding version of a standard electric guitar, and many models are built with a scale length of exactly 27 inches, measured from the nut to the bridge.

8. A 27-Inch Kitchen Sink
Many kitchen sinks are sold in a 27-inch width, a handy size for smaller kitchens and utility rooms where a full-size sink will not fit. The measurement is taken across the top of the sink from one side to the other.
Because these sinks are built around standard cabinet sizes, the 27-inch measurement is very consistent between brands. It is a practical example hiding in many homes.
9. Eight Credit Cards End to End

10. A Classic 27-Inch Road Bike Wheel
Older road bicycles were built around 27-inch wheels, a vintage standard that was common for decades. The number describes the diameter of the wheel, tyre included, measured straight across.

Wall clocks are sold in many standard sizes, and 27 inches is a common diameter for oversized home, office, and garden clocks. A clock this wide makes a real statement on a large wall.

Smaller televisions for bedrooms, kitchens, and caravans are still sold in a 27-inch size. Like monitors, a TV is measured diagonally across the screen, so a 27-inch TV measures exactly that.
Many people grew up with a set about this size in the house. If you remember an older bedroom television, you already have a good picture of 27 inches.
16. A Bar Stool Seat Height
Bar stools are commonly sold with seat heights in the mid to high twenties, and many models sit right around 27 inches from the floor to the top of the seat. It is a comfortable height for kitchen islands and breakfast bars.

How to Measure 27 Inches Without a Ruler
You do not always need a ruler to estimate 27 inches. The best trick for this size uses something in your wallet: a credit card is 3.37 inches long, so eight credit cards laid end to end in a straight line give you 26.96 inches, which is almost exactly 27 inches.
Paper works well too. Two letter-size sheets placed end to end give you exactly 22 inches, and adding about five thumb widths, at roughly an inch each, lands you very close to 27 inches.
You can also use a standard tennis racket or a large checked suitcase if you have one at home, since both are made to about 27 inches. Standing the case against a wall gives you a ready-made measuring guide for furniture and parcels.
