Perimeter of Regular Octagon Calculator

Are you looking for a simple and accurate way to calculate the perimeter of a regular octagon? Our Perimeter of Regular Octagon Calculator makes it easy to find the total boundary length of any octagon in just one click. Whether you are working on mathematics problems, architecture designs, fencing projects, tiling, or craftwork, this tool saves time and ensures precise results without manual effort.

📏 Understanding the Regular Octagon

Regular Octagon:
An octagon is a polygon with 8 equal sides and 8 equal angles. A regular octagon means all its sides and interior angles are equal, making it a symmetrical and balanced shape.
Interior angle of a regular octagon = 135°
Total number of sides = 8

Perimeter of an Octagon:
The perimeter simply refers to the sum of all side lengths. Since a regular octagon has equal sides, the formula becomes straightforward.
👉 Conversion Formula:
Perimeter = 8 × Side Length
This makes it extremely simple to calculate the total length around an octagon once you know the measurement of one side.

⚖️ Formula to Calculate the Perimeter of a Regular Octagon

P = 8 × a

Where:
P = Perimeter of the octagon
a = Length of one side
All you need to do is multiply the side length by 8, and you instantly get the perimeter.

📚 Examples of Regular Octagon Perimeter Calculation

Example 1: Side = 4 cm

P = 8 × 4 = 32 cm

✅ So, a regular octagon with side 4 cm has a perimeter of 32 cm.

Example 2: Side = 12 meters

P = 8 × 12 = 96 m

✅ A regular octagon with side length 12 m has a perimeter of 96 meters.

Example 3: Side = 7.5 feet

P = 8 × 7.5 = 60 ft

✅ A regular octagon with side length 7.5 ft has a perimeter of 60 feet.

Example 4: Side = 25 mm

P = 8 × 25 = 200 mm

✅ A regular octagon with side 25 mm has a perimeter of 200 mm.

These examples show how quick and versatile the calculator is, no matter the measurement unit (cm, m, ft, mm).
