A rectangle face shape is longer than it is wide, with a forehead, cheekbones and jawline of similar width and a defined, angular jaw. For men, the most flattering haircuts add width at the sides and keep height on top in check: think medium side parts, textured crops, natural waves, softer slick-backs, layers and fringes.
This guide is written for barbers, stylists and men's grooming brands. It goes straight to the six cuts that work, the styles to steer clients away from, and the glasses and beards that complete the look.
At a glance
- Goal: add visual width and break up vertical length.
- Keep the sides medium rather than skin-tight, and limit height on top.
- Fringes, side parts and texture all interrupt the long vertical line.
- Round, oval and browline frames and cheek-fuller beards help balance proportions.
What Is a Rectangle Face Shape?

A rectangle face, also called an oblong face, has three consistent traits:
- Length over width: the face is noticeably longer than it is wide.
- Straight sides: forehead, cheekbones and jawline are roughly the same width.
- Angular jaw: like a square face, the jaw is strong with defined corners.
Not sure whether a client is rectangle, square or oval? Our face shape test walks through the measurements, and the men's face shape guide compares all six core shapes side by side.
The Best Haircuts for Men with a Rectangle Face Shape
Each cut below works by adding width at the sides, softening angles, or shortening how long the face appears.
1. Medium Length with Side Part
This classic lets hair fall slightly over the forehead and keeps volume at the sides, which visually widens the face. The diagonal line of the side part breaks up the face's vertical length.
2. Textured Crop with Tapered Sides
A modern, low-maintenance option. Length on top gives styling flexibility, a forward-pushed texture keeps height down, and a soft taper (rather than a high skin fade) stops the sides from looking too narrow.
3. Wavy or Curly Styles
Natural waves and curls add width and softness on their own. Encourage clients with texture to keep enough length at the sides for that volume to show, and shape the top so it spreads outward rather than upward.
4. Slicked Back with Medium Sides
A tight slick-back with an undercut can exaggerate length, which is why many grooming guides list it as one to avoid. Pairing a softer, low-shine slick-back with medium-length sides keeps the polish while maintaining balance.
5. Layered Styles
Layers create movement and prevent a heavy, one-length outline. Placing them around the temples and ears adds visual width exactly where a rectangle face needs it.
Haircuts to Avoid with a Rectangle Face
Styles that add height or remove width tend to lengthen a rectangle face further. FashionBeans flags pompadours, flat tops, long straight hair and slicked-back hair as risky choices. In practice, also watch for:
- High skin fades or very short sides combined with volume on top
- Tall quiffs and spiked styles
- Long, flat, center-parted hair that draws the eye downward

Glasses and Beards That Balance a Rectangle Face
Glasses
Frames with more lens height and some width help counter the face's length. Good starting points include:
- Round frames
- Oval frames
- Browline frames
These shapes contrast with angular features. Avoid very narrow, thin frames, which can stretch the face. See our guide to the best glasses for oblong face shapes for ten frame styles.
Beards
Facial hair can rebalance proportions. To add width, suggest fuller, rounded beards or heavy stubble that builds density on the cheeks. To shorten length, keep the chin trimmed rather than pointed, so the beard reads wider at the jaw than it is long.

Rectangle Face Shape FAQ
Is a rectangle face the same as an oblong face?
Yes. Both terms describe a face that is longer than it is wide with similar widths across the forehead, cheekbones and jaw. Some guides use "rectangle" when the jaw is especially angular.
What hair length suits a rectangle face for men?
Short-to-medium lengths with fuller sides usually work best. Very long, straight hair and tall styles on top tend to add length.
Should men with a rectangle face grow a beard?
A beard is optional, but one that is fuller on the cheeks and kept short at the chin can add width and soften a long jawline.
How is a rectangle face different from a square face?
Both have an angular jaw and straight sides, but a square face is about as wide as it is long, while a rectangle face is clearly longer.
