Bob vs Lob: How to Choose the Right Length for Your Face
Last updated: April 2026
A bob ends at the chin or jaw for a dramatic, face-framing cut — a lob (long bob) extends to the collarbone for a more versatile, lower-commitment length. Bobs offer 12 distinct variations in our catalog but most have face shapes to avoid. Lobs work for virtually everyone — 2 of 3 have zero shapes in the “avoid” list. Lobs also need trims only every 8.0 weeks vs 5.9 for bobs.

When to Choose a Bob
A bob is the right move when you want a bold, face-defining cut with maximum impact. With 12 variations — from the sleek blunt bob to the textured shaggy bob — there's a bob for virtually every hair texture. 33% of bob styles elongate the face, while 42% soften the jawline.
Oval, heart, or diamond face
These shapes suit the widest range of bobs. Oval scores "best" across 11/12 styles, heart across 7, diamond across 3.
You want a dramatic change
Going from long hair to a bob is a statement. The shorter length immediately transforms your look — bobs are the most recognized "big chop" cut for a reason.
Fine or thin hair
Blunt bobs and a-line bobs create maximum density at the ends. The shorter length means less weight pulling hair flat, so fine hair looks fuller and thicker.
You want face-defining angles
33% of bobs elongate the face and 42% soften the jawline — choose based on which effect you want.
When to Choose a Lob
The lob is the safest, most versatile mid-length cut. 2 of 3 lob styles have zero face shapes in the “avoid” category — making the lob the closest thing to a universally flattering haircut. At 8.0 weeks between trims, it's also significantly lower maintenance than bobs.
Any face shape — especially round
The lob is one of the few cuts that works for every face shape. For round faces specifically, the length past the chin creates a slimming vertical line that short bobs can't match.
You want flexibility
A lob is long enough to tie back in a ponytail, braid, or updo. Bobs can't. If you need versatility for work, workouts, or events, the lob gives you options a bob doesn't.
Low maintenance preference
At 8.0 weeks between trims, lobs need fewer salon visits. They also grow out more gracefully — there's no awkward in-between stage like there is when growing out a short bob.
Testing shorter hair for the first time
If you've always had long hair, a lob is the perfect transition cut. You get the "went shorter" transformation without the full commitment of a chin-length bob.

Bob vs Lob by Face Shape
Your face shape is the single biggest factor in choosing between a bob and a lob. Here's what our metadata says:
Round Face
Lob winsBob: Risky — 8/12 bobs list round as "avoid." If you must bob, go A-line or asymmetrical for elongation.
Lob: Excellent. The length past the chin slims and elongates. The lob is the #1 recommended cut for round faces.
Oval Face
Either winsBob: 11/12 bobs score "best." Oval faces can wear any bob type — go with your style preference.
Lob: Also "best" across all lob styles. Truly a toss-up for oval faces.
Heart Face
Bob winsBob: 7/12 bobs score "best" — chin-length bobs add visual weight at the narrow jaw, balancing a wider forehead.
Lob: Good, but the extra length doesn't add jaw-level width the way a bob does.
Square Face
Either winsBob: 2/12 score "best." Layered and shaggy bobs soften strong jawlines. Avoid blunt bobs that emphasize the jaw.
Lob: Works well. The softness of a lob complements angular features without highlighting the jawline.
Long / Oblong Face
Bob winsBob: 6/12 score "best." Short bobs with volume (french bob, italian bob) add width and shorten the face.
Lob: Can make a long face appear even longer. Choose a lob only with layers or waves for width.

Frequently Asked Questions
What is the difference between a bob and a lob?
A bob ends between the chin and jaw — a lob (long bob) extends to the collarbone or shoulders. Our catalog has 12 bob variations and 3 lob styles. The key practical difference: bobs are more dramatic and shape-specific (most have face shapes to avoid), while lobs are universally flattering — 2 of 3 lob styles have zero face shapes in the "avoid" category. Bobs average 5.9-week trims; lobs average 8.0 weeks.
Is a lob or bob better for a round face?
A lob is the safer choice. The lob scores "best" for round faces because the extra length below the chin creates a slimming vertical line. Most short bobs add width at the jawline, which can emphasize roundness — 8 of 12 bob styles list round as a shape to avoid. If you want a bob on a round face, choose an a-line bob or asymmetrical bob — both elongate the face rather than widening it.
Which is easier to maintain — a bob or a lob?
Lobs are lower maintenance overall. They average 8.0-week trim cycles compared to 5.9 weeks for bobs, and 2 of 3 are rated "low maintenance." Bobs vary widely — a shaggy bob is low-maintenance (grows out gracefully), but a sleek bob or micro bob needs frequent trims to stay sharp. 4 of 12 bob styles are rated "high maintenance." The lob also gives you the option to tie hair back on lazy days, which bobs can't.
Can I get a bob with curly hair?
Yes — the curly bob in our catalog is specifically designed for types 3A-3C. Curly bobs create a voluminous, rounded silhouette that softens angular features. The wavy bob works for 2A-2C textures. For tighter curls, keep in mind that curl shrinkage makes the bob appear shorter than it's cut — communicate your desired dry length to your stylist. A lob is a safer first step for curly hair since the extra length gives curls more room to form.
Will a bob make my face look wider or thinner?
It depends on the type. 33% of our bob styles elongate the face (blunt bob, sleek bob, a-line bob, asymmetrical bob) — these make your face look thinner. 58% add width (layered bob, shaggy bob, curly bob, italian bob) — these make your face look wider, which actually benefits long or oblong faces. A lob has a neutral face effect — it doesn't significantly alter perceived width or length, making it the safest option if you're unsure.
Should I get a bob if I have fine hair?
A blunt bob is one of the best cuts for fine hair. The one-length perimeter creates maximum density at the ends, making hair look thicker. Our blunt bob and a-line bob both carry the "good for thin hair" tag. Avoid heavily layered bobs on fine hair — removing weight from already-thin ends makes them look wispy. A lob with a blunt cut is another excellent option for fine hair, with the added benefit of lower maintenance.
