9 Things that are 4 meters long
A meter is often compared to a yard, which is equal to 3 feet in length, although a yard and a meter are not exactly equal. Four meters is closer to about 13 feet.
Picturing 4 meters can be challenging for people who don’t regularly use the metric system, but having some handy examples can help.

A Sedan
In general, vehicles average about 14 feet long, but many compact cars are closer to 13 feet or 4 meters in length.
Picturing a car is one of the easiest ways to quickly estimate 4 meters with relative accuracy. You can also use a vehicle’s width to estimate 4 meters.
Most cars are at or just over 6 feet in width, which is very close to 2 meters. You only need to picture two cars parked side by side to use the cars’ widths to visualize 4 meters.

Two Mattresses
Four meters is equal to about 13.1 feet or around 157 inches. King and queen mattresses are exactly 80 inches long, while full mattresses are 75 inches long.
Therefore, two full mattresses, lined up end to end, would equal just less than 4 meters in length, while two king or queen mattresses would be just over 4 meters in length.

Half the Length of a School Bus
Most school buses are between 20 and 35 feet long. An average or medium-sized bus is usually around 25 feet long, which is equal to just under 8 meters.
Picturing half of a regular school bus can help you visualize a length that’s very close to 4 meters.

An African Elephant
African elephants are the largest elephant species and the largest living land animals. They can weigh between 6,000 and 13,000 pounds and can grow to a height of 8 to 13 feet.
This means that the largest African elephants are often right around 4 meters tall.
African forest elephants are usually smaller than African bush elephants, as forest elephants must be small enough to make their way through dense undergrowth and around trees and bushes.
Bush elephants, however, can grow to a larger size, as they live in more wide-open spaces. Male elephants are usually a couple of feet taller than female elephants.

Two Yoga Mats
A yoga mat must be long enough for the person using it to stretch out fully, without any overhang of the head or feet.
For this reason, most yoga mats are about 6 feet long, although oversized yoga mats, designed for taller people, are a few inches longer.
Picture yoga mats laid out in two rows, as they might be in a typical yoga class, and think about the distance between the foot of the first mat and the head of the mat in the second row.
This distance, spanning the length of the two mats, is probably about 4 meters.

A T-Rex’s Hips
Tyrannosaurus Rex, more commonly called the T-Rex, was one of the most fearsome dinosaurs of the Cretaceous Period.
T-Rex is also one of the most well-known dinosaurs and, thanks to books and movies, it’s relatively easy to picture.
The Tyrannosaurus Rex was a massive dinosaur with a long body and tail.
Because of its powerful legs and long build, this dinosaur often stood with its head and tail parallel to the ground, making its strong hips the highest point on its body.
Scientists often measure this creature’s height to the top of its hips because of this. Many T-Rex were about 13 feet or 4 meters tall at the hips.
If they stood upright, they would have been taller, but this position would most likely have caused a small loss of balance for the animal.

A Bottlenose Dolphin
The common bottlenose dolphin, which is probably the most recognizable dolphin species, can grow to between 6.6 and 13 feet long.
The longest bottlenose dolphin would be almost exactly 4 meters in length, while you would need two shorter dolphins to add up to around 4 meters in length.
Common bottlenose dolphins are one of the largest dolphin species, with other species averaging around 7 feet in length.
Notable exceptions include pilot whales, which are a member of the dolphin family but can grow to between 17 and 18 feet long, and orcas, another dolphin family member, which can grow to between 20 and 26 feet long.
Unlike many other mammal species, female dolphins tend to be larger than male dolphins.
Dolphins are thought to be some of the smartest animals on the planet. They are capable of learning and teaching, and they can plan and cooperate.

Two Couches
Couches can be of various sizes depending on how they’re made, whether they’re designed to be sleek or overstuffed, or whether they have two or three cushions or seats.
In general, though, most couches are between 72 and 96 inches. Average couches are usually around 84 inches in length, which is about 7 feet.
This means that most small or average couches are either just shorter or just longer than 2 meters.
Two couches side-by-side would equal about 4 meters in length.

Two Charging Cables
Charging cables are available in many different lengths, which can help you organize an area or make charging devices more convenient.
One of the most common charging cable lengths is 72 inches or 6 feet.
Stretching two of these cables and placing them end to end would show you a length that is just short of 4 meters.
