Hat Size Calculator
Finding the right hat size can often be a challenge, especially when shopping online or crafting personalized hats. The hat size calculator helps you accurately determine your hat size based on your head circumference, ensuring a perfect fit every time.
Formula
The formula to calculate hat size is:
Hat Size (HS) = Head Circumference (H) / π
How to Use
- Measure your head circumference using a tape measure, ensuring it wraps snugly around your head above your ears and across the forehead.
- Input the head circumference in centimeters into the calculator.
- Click the “Calculate” button to get your hat size.
- Use the result to select hats that fit comfortably.
Example
If your head circumference measures 58 cm, the calculation will be:
HS = 58 / π ≈ 18.46
Your hat size would be approximately 18.46.
