How Long Is 3 Feet? 1 Yard in CM, Inches and Real Objects

Quick answer: 3 feet is exactly 1 yard, or 36 inches, which equals 91.44 centimetres (0.9144 m). To picture it, 3 feet is the height of a standard US kitchen counter, the width of a front door, and about the height of an average 3-year-old child.

Three feet – one yard – is the length used for fabric, carpets, sports fields and many building standards in the US. It is also close to a metre, which causes plenty of confusion. This guide covers the conversion, how a yard compares with a metre, everyday objects that are about 3 feet long, and where the measurement shows up in homes and buildings.

How to convert 3 feet to inches and cm

• Feet to inches: 3 × 12 = 36 inches.
• Feet to centimetres: one foot is exactly 30.48 cm, so 3 × 30.48 = 91.44 cm.
• Feet to metres: 91.44 ÷ 100 = 0.9144 m.
• Feet to yards: a yard is defined as 3 feet, so 3 feet = 1 yard.

Is 3 feet the same as 1 metre?

No, although the two are often treated as if they were. A metre is 100 cm and 3 feet is 91.44 cm, so a metre is about 8.6 cm (3.4 inches) longer – roughly the width of a credit card’s short side plus a bit more.

The difference adds up quickly. A 100-yard American football field is 91.44 m, so a 100-metre sprint is almost 9.4 yards longer than the field.

3 feet compared to everyday objects

• Kitchen counter: the standard height of a US kitchen worktop is 36 inches – exactly 3 feet from the floor.
• Door width: a standard US front door is 36 inches wide. A standard interior door is narrower at 32 inches (813 mm), so 3 feet is about 10 cm wider than the interior door leaf.
• Office desk: a typical office desk is 1,400 mm wide, so 3 feet reaches about two-thirds of the way across.
• Rulers: three 12-inch rulers end to end are exactly 3 feet. A yardstick is the same length in one piece.
• Laptops: about three 14-inch MacBook Pros (31.3 cm wide each) side by side.
• 50-inch TV: a 50-inch TV is about 1,107 mm wide, so 3 feet is about 19 cm narrower than the screen.
• King mattress: 3 feet is a little less than half the length of a king mattress (80 inches).
• Guitar: a full-size acoustic guitar is about 38-41 inches long, just over 3 feet.
• Child: the average 3-year-old is about 37-38 inches (95 cm) tall, a little over 3 feet.

Where 3 feet is a standard size

• Hallways: US residential building codes usually require hallways to be at least 36 inches wide.
• Railings and balconies: guards on decks and balconies in many US homes must be at least 36 inches high.
• Fabric and carpet: in the US, fabric is still sold “by the yard”, so each yard you buy is 36 inches long.
• Clearance: 36 inches is a common recommended walking space around beds, tables and kitchen islands.
• Sport: American football fields are 100 yards (300 feet) between the goal lines, and golf distances in the US and UK are measured in yards.

According to a popular story, King Henry I of England defined the yard as the distance from his nose to the tip of his outstretched thumb. Whether or not it is true, nose-to-fingertip with your arm held out sideways is still a quick way to estimate a yard for many adults. Today the yard is defined exactly as 0.9144 m, under the 1959 international agreement.

How to measure 3 feet without a tape measure

1. Arm’s length: hold one arm out to the side and measure from your nose to your fingertips. For many adults this is close to a yard.
2. Stride: a long walking step for an adult is roughly 3 feet. Practise once against a tape measure to calibrate your own stride.
3. Paper: three sheets of US Letter paper end to end (33 inches) plus a credit card’s length (3.4 inches) is just over 3 feet.
4. Kitchen counter: in most US kitchens, the counter top is 36 inches off the floor, so you can use it as a reference.
