Curtain Bangs vs Side Bangs: Which Frames Your Face Better?
Last updated: April 2026
Curtain bangs part at the center and sweep outward to frame both sides of the face symmetrically — side bangs sweep diagonally to one side, creating an asymmetric line. Curtain bangs are the most universally flattering: 2 of 3 styles have zero face shapes in the “avoid” list. Both average 4-5 week trim cycles, but curtain bangs grow out more gracefully into face-framing layers.

When to Choose Curtain Bangs
Curtain bangs are the most forgiving, universally flattering bang type in our catalog. 2 of 3 curtain bang styles have zero face shapes to avoid. They grow out gracefully into face-framing layers and work with straight, wavy, and curly hair (our curly curtain bangs cover types 2C-3C).
Round, oval, or heart face
Curtain bangs score "best" for all three. The center part creates a vertical line that elongates round faces, while the outward sweep highlights cheekbones on heart and oval shapes.
You want low-commitment bangs
Curtain bangs are the easiest to grow out. As they lengthen, they naturally transition into face-framing layers — no awkward in-between stage like blunt or side bangs.
Straight to wavy hair (1B-2B)
This is the sweet spot for curtain bangs. The natural weight and texture create the signature outward sweep. For curly hair (2C-3C), our curly curtain bangs variant works beautifully.
You want to soften a large forehead
3/3 curtain bang styles cover the forehead partially — concealing the temples and edges while leaving the center open. A subtler effect than full blunt bangs.
When to Choose Side Bangs
Side-swept bangs create a diagonal line that breaks facial symmetry and creates the illusion of length. They're the only bang type in our catalog that scores “best” for round faces, square faces, and heart faces simultaneously — making them uniquely versatile for angular and rounded shapes alike.
Round or square face
The diagonal line is the most effective shape-breaking tool. It disrupts the circular symmetry of round faces and softens the strong angles of square faces — blunt and curtain bangs can't match this asymmetric effect.
You want face elongation
Side-swept bangs elongate the face and soften the jawline simultaneously. The diagonal sweep draws the eye downward along the cheekbone, creating perceived length.
You have a wide forehead
The deep side part places more hair on one side of the forehead, visually narrowing it. The diagonal coverage conceals width more effectively than centered curtain bangs.
Classic, polished aesthetic
Side bangs read more formal and polished than curtain bangs. They pair well with sleek bobs, corporate styles, and evening looks. Curtain bangs lean more bohemian and relaxed.

Frequently Asked Questions
What is the difference between curtain bangs and side bangs?
Curtain bangs are center-parted and sweep outward from the middle of the forehead, framing both sides of the face symmetrically — like opening a curtain. Side bangs are swept entirely to one side with a deep side part, creating an asymmetric diagonal line across the forehead. In our catalog, 2 of 3 curtain bang styles work for ALL face shapes (zero shapes to avoid), making them the most universally flattering bang type. Side bangs are equally versatile with 1/1 working for all shapes. The biggest practical difference: curtain bangs grow out into face-framing layers seamlessly; side bangs require more frequent reshaping to maintain the diagonal.
Which is better for a round face — curtain bangs or side bangs?
Both work well, but for different reasons. Curtain bangs score "best" for round faces — the center part creates a vertical line that elongates the face, while the outward sweep adds angles at the cheekbones. Side-swept bangs also score "best" for round faces — the diagonal line breaks up the face's circular symmetry and creates the illusion of length. If you want a modern, symmetrical look, go curtain. If you want asymmetric slimming, go side-swept.
Are curtain bangs easier to maintain than side bangs?
They're roughly equal in trim frequency — curtain bangs average 5.0 weeks between trims, side bangs 4.0 weeks. But curtain bangs win on grow-out: as they lengthen, they naturally transition into face-framing layers and still look intentional. Side bangs that grow out lose their diagonal shape and start falling into the eyes awkwardly. For the lowest-maintenance bang option in our catalog, wispy bangs (4-week trims) or a french bob with built-in bangs are your best bets.
Can I get curtain bangs with curly hair?
Yes — our curly curtain bangs style is specifically designed for types 2C-3C. Curly curtain bangs create soft, bouncy face-framing pieces that part naturally around the forehead. The key difference from straight curtain bangs: curly versions frame the cheekbones and temples with springy ringlets rather than a smooth sweep. They work best for oval, heart, and diamond faces. Ask your stylist to cut them dry to account for curl shrinkage — wet-cut curly bangs can end up much shorter than expected.
Will bangs make my forehead look smaller?
Yes — all bang types cover the forehead to some degree. Curtain bangs cover partially (temples and edges) while leaving the center open, which is ideal if you want forehead reduction without complete coverage. Side-swept bangs create a diagonal line that partially conceals one side. For maximum forehead coverage, blunt bangs or wispy bangs cover the entire forehead. Our catalog tags 3/3 curtain styles and all side-swept styles as "covers forehead." All are tagged as "good for big forehead."
Which bangs are trending in 2026?
Curtain bangs continue to dominate — they've been the #1 bang trend since 2023 and show no signs of slowing down. The curly curtain bang variant is gaining momentum as the natural hair movement grows. Wispy bangs (the "barely there" Korean-inspired look) are surging for their low-commitment appeal. Side-swept bangs are a classic that cycles back periodically — currently experiencing a revival through Y2K and early-2000s nostalgia aesthetics.
Can I try curtain bangs or side bangs on my photo before cutting?
