The Simplest Method to Find Thirty Centimeters?

Drive the car to the starting point with the front wheels crossing the yellow line. Keep one side of the vehicle approximately 1.5-1.8 meters away from the sideline, then turn the steering wheel fully to the right and reverse. While reversing into the parking space to the right, observe the right-side rearview mirror. As the vehicle moves backward, when the right rear wheel aligns with the extended line of the parking space, turn the steering wheel fully to the right. After entering the parking space, the distance on both sides should generally be maintained at around 30 centimeters.

What's the easiest way to measure 30 centimeters? I find this task super simple. As an avid car repair enthusiast, I just use my own hands—my palm is about 10 centimeters wide, so three palms side by side make 30 centimeters. Sometimes when adjusting engine clearances in the garage, I first estimate with my hands and then double-check with a tape measure, saving time and ensuring accuracy. The best part is not needing expensive tools—it's always handy. Pay attention to the distance between the tire and the body too; measure often, and you'll naturally memorize the dimensions. Give it a try—it's guaranteed to be convenient.

Want to measure thirty centimeters? Here's how I do it: keep a small tape measure in the car. As a practical person, I find this method the simplest and least effort. For example, when parking to avoid scratches, measure the space in front and behind—about 30 centimeters is just the right safe distance. Tape measures are cheap and easy to carry. A friend of mine once estimated by hand and ended up hitting a wall, so having a simple tool is crucial. The same goes for routine maintenance, like checking brake pad thickness. Remember, accuracy helps avoid mistakes—it's a worthwhile investment.

I think a simple method is to use body parts. The length from the shoulder to the fingertips is about 60 centimeters, and half of that is 30 centimeters. I often use this method to quickly measure wheel gaps in the garage. Although it's not precise, it's sufficient for daily tasks, such as parking or checking parts. This trick avoids the hassle of tools and is easy for beginners to learn. With practice, you'll develop a feel for it, and it's quite practical.
