The Definitive 7-Step Measurement Method (The Traditional Way)

Before relying on a modern AI Face Shape Detector, the most reliable way to determine your shape is by taking four key facial measurements. You will need a flexible measuring tape (the kind used for sewing), a mirror, and a notepad. Do this with your hair pulled back from your face.

1. Measure Your Forehead: Find the widest point across your forehead, typically halfway between your eyebrows and your hairline. Note this number.
2. Measure Your Cheekbones: Measure across the highest part of your cheekbones, starting and ending at the sharp point just below the outer corner of each eye. This is often the widest measurement on the entire face.
3. Measure Your Jawline: Measure from the tip of your chin up to the point where your jaw angles upward (just below your ear). Multiply this number by two to get the total jawline width.
4. Measure Your Face Length (Vertical): Measure from the center of your hairline (or where it would be) straight down to the very bottom of your chin. This is your face length.
5. Compare the Measurements: Analyze the four numbers you’ve recorded. Which is the longest? Which is the shortest? The relationship between these four measurements is the key to identifying your unique facial structure.
6. Observe Your Jawline and Chin: Is your jawline soft and rounded, or sharp and angular? Is your chin pointed, square, or rounded?
7. Determine the Shape: Use the comparison guide below to match your results to one of the six main face shapes.

The 6 Main Face Shapes and Their Defining Features

Once you have your measurements, match your dominant features to one of these core shapes.

Oval Face Shape

The Oval Face Shape is considered the most versatile and balanced. The face length is noticeably longer than the cheekbone width, and the forehead is wider than the jawline. The jawline and chin are gently rounded, creating a soft, symmetrical look.

• 2025 Style Tip: Almost any style works, but long layers and a mid-length cut with face-framing layers are particularly flattering to show off the perfect symmetry.

Round Face Shape

The Round Face Shape is defined by having the face length and cheekbone width almost equal. The jawline and chin are soft, without sharp angles, creating a circular appearance. The forehead is often rounded.

• 2025 Style Tip: The goal is to add length and definition. A voluminous pixie cut or a long, sleek style can elongate the face. Avoid chin-length bobs that add width.

Square Face Shape

The Square Face Shape is strong and angular. All four measurements (forehead, cheekbones, jawline, length) are relatively similar, but the defining feature is the prominent, broad, and angular jawline.

• 2025 Style Tip: Softness is key. A soft shag or long, sweeping side-swept bangs can soften the strong jawline. A chin-length bob can also work if it has movement.

Heart Face Shape

The Heart Face Shape (sometimes called an inverted triangle) is widest at the forehead and tapers down to a narrow, pointed chin tip. The cheekbones are prominent, and the forehead is the most dominant feature.

• 2025 Style Tip: Hairstyles should aim to balance the wider forehead. Side-swept bangs, a deep side part, or a long bob (lob) that hits below the chin are excellent choices.

Diamond Face Shape

The Diamond Face Shape is characterized by a narrow forehead and jawline, with wide and high cheekbones being the widest part of the face. The chin is often pointed. This is a highly angular and striking shape.

• 2025 Style Tip: Styles that add width to the forehead and jawline are best. A deep side part, a textured bob, or a wolf cut with volume at the top can be very flattering.

Oblong or Rectangle Face Shape

The Oblong Face Shape (also called Rectangle) is similar to the oval shape, but the face length is significantly longer than the cheekbone width. All four measurements are often similar, but the face is long and narrow.

• 2025 Style Tip: The goal is to create the illusion of width. Bobs, face-framing layers, and bangs (fringe) that cover the forehead are ideal for shortening the appearance of the face.

The Modern Approach: AI Face Shape Detector Tools

In 2025, the most cutting-edge and accurate way to get an answer to "whats my face shape" is through artificial intelligence (AI) face analyzers. These tools, often found in apps like Facetune or dedicated online detectors, use sophisticated facial landmark measurements to provide an objective analysis.

The AI technology works by analyzing a photo you upload, measuring key points like the distance between your pupils, the angle of your jawline, and the curve of your chin. This approach removes the subjectivity of traditional mirror-and-ruler methods, giving you a precise result and often providing personalized recommendations for hairstyles, makeup placement, and eyewear.

While the traditional method provides a great foundational understanding, the AI face shape detector offers a quick, modern, and highly accurate result, making it the preferred method for many style experts today.

Beyond Hair: Choosing Flattering Glasses and Makeup

Knowing your face shape is a powerful tool that extends far beyond your next haircut. It’s critical for selecting the right eyewear and applying makeup that enhances your natural beauty.

Eyewear Selection for Your Face Shape

The golden rule for glasses is to choose frames that contrast with your face shape to create balance and visual interest.
For Round Faces: Choose angular, rectangular, or cat-eye glasses to add definition and lengthen the face.
For Square Faces: Opt for round or oval frames to soften the strong jawline and forehead.
For Oval Faces: Most shapes work, but avoid frames that are too large, which can throw off your symmetry.
For Heart/Diamond Faces: Rimless or bottom-heavy frames can balance a wider forehead and draw attention to the lower half of the face.

Strategic Makeup Placement

Contouring and highlighting are entirely dependent on your face shape. The goal is always to create the illusion of the balanced, slightly elongated Oval Face Shape.

• Round Faces: Apply contour powder along the sides of the forehead and down the sides of the face (from the temples to the jawline) to create a slimming effect and add angularity.
• Square Faces: Apply contour to the corners of the jaw and the sides of the forehead to soften the strong lines. Highlight the center of the face.
• Oblong Faces: Apply contour horizontally under the chin and at the top of the forehead to visually shorten the face. Avoid highlighting the bridge of the nose, which adds length.

By using the 7-step guide or a modern AI detector, you can accurately identify your facial structure. This knowledge is the single most effective way to ensure every style choice you make—from a trendy 2025 wolf cut to a new pair of aviator glasses—is perfectly suited to your unique features, giving you a look that is confidently and authentically you.
