Face Shape Calculator – Check Your Face Shape App by Omni

Measure the width of your forehead at its widest point.
Measure the distance between the outer edges of your cheekbones.
Measure from the tip of your chin to below your ear where the jaw angles upwards.
Measure from the center of your hairline to the tip of your chin.

We designed face shape calculator to analyze your face into common shapes like round, oval, square, oblong, heart, diamond, or triangle.

Types of Face Shapes

The most common face shapes include:

  • Oval: Considered the ideal face shape, characterized by balanced proportions and a slightly curved jawline.
  • Round: Features soft angles and equal width and length measurements.
  • Square: Defined by a strong jawline and equal width across the forehead, cheekbones, and jaw.
  • Rectangle: Similar to square but longer, with a forehead, cheeks, and jawline of similar width.
  • Heart: Wider at the forehead and cheekbones, tapering to a narrow chin.
  • Diamond: Narrow forehead and jawline with prominent cheekbones.
  • Triangle: Narrow forehead with a wider jawline.

Face Shape Formula

To determine your face shape, use the following formula:

Measure the following distances in centimeters:

Face length (FL): Hairline to chin

Forehead width (FW): Widest part of forehead

Cheekbone width (CW): Widest part of cheekbones

Jawline width (JW): Corner to corner of jaw

Calculate ratios:

Length-to-Width Ratio (LWR) = FL / CW

Jawline Ratio (JR) = JW / CW

Forehead Ratio (FR) = FW / CW

Use these ratios to determine your face shape:

Oval: LWR > 1.5, JR ≈ 0.8, FR ≈ 1

Round: LWR ≈ 1, JR ≈ 1, FR ≈ 1

Square: LWR ≈ 1, JR ≈ 1, FR ≈ 1

Rectangle: LWR > 1.5, JR ≈ 1, FR ≈ 1

Heart: LWR ≈ 1.5, JR < 0.8, FR > 1

Diamond: LWR ≈ 1.5, JR < 0.8, FR < 1

Triangle: LWR ≈ 1, JR > 1, FR < 1

How Do I Check My Face Shape?

To check your face shape:

Gather tools: You’ll need a flexible measuring tape, pen, and paper.

Pull back hair: Ensure your hairline and jawline are visible.

Take measurements: Record FL, FW, CW, and JW as described above.

Calculate ratios: Use the formulas to find LWR, JR, and FR.

Compare results: Match your ratios to the face shape descriptions.

If your measurements are FL = 22cm, FW = 15cm, CW = 14cm, and JW = 12cm:

LWR = 22 / 14 = 1.57
JR = 12 / 14 = 0.86
FR = 15 / 14 = 1.07

These ratios most closely match the oval face shape criteria.
