To identify a triangle face shape, measuring the proportions of the jawline, cheekbones, and forehead is essential. Using a flexible measuring tape:

1. Face length: Measured from the center of the hairline to the tip of the chin.
2. Forehead width: Measured at its widest point, typically halfway between the eyebrows and hairline.
3. Cheekbone width: Measured from one cheekbone’s outer corner to the other.
4. Jawline width: Measured from the chin to just below the ear, then multiplied by two.

If the jawline width is the largest measurement, followed by the cheekbones, with the forehead being the narrowest, then the face falls into the triangle category. This shape is different from an inverted triangle, where the forehead is widest and the jawline is the narrowest.

The goal for hairstyles with a triangle face shape is to add volume at the top while keeping the sides sleek to balance the strong jawline. The most flattering styles include:

• Pompadour: A classic choice that creates height and volume.
• Textured Quiff: Adds lift while keeping a natural, relaxed feel.
• Side-Swept Undercut: Keeps the sides short while directing focus upward.
• Textured Crop: A low-maintenance style that still adds shape and volume.
• Medium-Length with Layers: Softens the angles and allows for versatile styling.

Avoid styles like buzz cuts, slicked-back hair, or center parts, as they emphasize the jawline’s width and create an unbalanced look.

Beard styles should focus on softening the jawline and adding proportion to the upper face. The best options include:

• Full Beard: Reduces the prominence of a strong jaw.
• Circle Beard: Draws attention to the center of the face, evening out the angles.
• Short Stubble: A subtle choice that defines the jawline without adding bulk.
• Ducktail Beard: Extends the chin slightly for a more elongated face.
• Bandholz Beard: A bold, full-coverage beard that reshapes facial proportions.

Beards like chinstraps and mutton chops should be avoided as they highlight the jawline’s width rather than balancing it.

A well-selected mustache can add balance by drawing attention to the mid-face rather than the jawline. The best options include:

• Handlebar Mustache: Creates width at the upper lip.
• Chevron Mustache: Provides a full, classic look that complements sharp angles.
• Walrus Mustache: Adds volume and softens the lower face.
• Pyramid Mustache: Balances the face by tapering toward the nose.

Avoid thin pencil mustaches, as they fail to provide contrast to the strong jawline.

Sunglasses should add width to the forehead and upper face while complementing the strong jawline. The most flattering styles include:

• Aviators: Enhance the brow area and create balance.
• Wayfarers: Their slightly wider top structure offsets the lower face’s sharpness.
• Round Frames: Soften angular features.
• Clubmasters: Draw focus to the forehead for a proportional look.

Avoid rectangular and oversized frames, as they can exaggerate the face's natural width at the jaw.
