Bubble bob vs box bob: the difference and how to ask
Both are short bobs, and both are searched for by name, but they are cut differently. A bubble bob is soft and round; a box bob is blunt and square. The easiest way to tell them apart is the bottom edge.
The two bobs side by side
| Bubble bob | Box bob | |
|---|---|---|
| Length | To the chin | To the jawline |
| Layers | Soft internal layers for a lifted, rounded outline | None: one length, cut blunt |
| Bottom edge | Ends bevelled under toward the chin | Straight across, keeping its full width |
| Fringe | None | None; a deep side part |
| Sides and back | About 13 cm sides, 10 cm back | About 15 cm sides, 14 cm back |
| Daily styling | Round-brush blow-dry | Little: comb through |
Hair textures and face shapes
Both are pictured on straight hair. In the catalog the bubble bob is usually cut on straight and wavy hair and the box bob on straight and wavy hair. A blunt box bob shows its edge most clearly on straight hair, and a bubble bob needs hair that can be blown into a round shape. The catalog lists oval, oblong, heart, diamond and square face shapes for the bubble bob, and does not suggest it for round. It lists oval, oblong, heart and diamond face shapes for the box bob.
What to tell your barber
Bubble bob: "chin length, soft internal layers for a round, lifted outline, bevel the ends under, no fringe." Box bob: "one length at the jawline, cut blunt and square with no layers so the bottom keeps its width, deep side part, no fringe." The words "no layers" and "internal layers" are the ones that separate them.

These lines are copied from the FitMyFace barber card. The values are suggested starting points, not reviewed by a barber, and your barber adapts them to your hair. The card records the look you want and starting measurements; your barber checks and adjusts the final cut. The picture is illustrative. To change a value, open the card and edit it.
Upkeep
The card's upkeep lines are typical guides, not rules. Bubble bob: haircut every 6–8 weeks, with about 10 minutes of blow-drying a day. Box bob: haircut every 6–8 weeks, with about 2–5 minutes of combing a day. Both lose their shape as the length grows past the chin or jaw, which is why they need the shorter 6–8 week cycle.
FitMyFace hair previews are approximations, not predictions of how your hair will lie after a cut. Ordinary hairstyle try-ons perform face analysis on-device. The optional AI previews (hair and glasses) send a photo to Cloudflare; your consent is the one "I agree" on the scan screen, and a switch on the results turns them off.

Questions
Which one is easier to style?
The box bob needs less: it is cut to sit straight, so a comb is often enough. The bubble bob needs a round brush and a blow-dry to get its shape.
Can I have a bob with a fringe?
Both catalog versions have no fringe. You can add one by asking your barber; the card has a fringe setting you can edit.
Can I try them first?
Yes, as AI pictures on your own photo, one after the other. They are illustrative. The card records the look you want and starting measurements; your barber checks and adjusts the final cut.
Each has its own page with the barber card: the bubble bob and the box bob.
