Cybex Libelle vs Stokke YOYO
One is the thinnest fold on this site. The other is the smallest. They are not the same stroller, and they are not the same answer.

The short answer
Buy the Cybex Libelle if the stroller has to fit in a confined space: Cybex publishes 12.6 x 7.8 x 18.9 in folded, which is roughly 1,860 cubic inches, and the brand describes it as small enough to fit inside a checked suitcase. Buy the Stokke YOYO if the stroller has to go into a shallow overhead bin: 7.1 in of folded depth is the thinnest on this site. The counterintuitive part is that the thinner stroller is the bigger one — the YOYO is about a third more volume folded.
Thin and small are different specifications
Compact-stroller marketing collapses two separate ideas into one word. “Folds small” can mean a flat slab or a tight brick, and the two behave completely differently once you are standing in an aisle.
The YOYO is a slab. Stokke publishes 52 x 44 x 18 cm — 20.5 x 17.3 x 7.1 in — and the 18 cm is what the folding handlebar buys you (stokke.com, read 2026-09-27). It slides edge-on into a bin that would not accept a thicker object.
The Libelle is a brick. Cybex publishes 200 x 320 x 480 mm folded — 12.6 x 7.8 x 18.9 in — at 5.9 kg, with unfolded dimensions of 710 x 520 x 1020 mm (cybex-online.com, read 2026-10-14). Nothing about it is especially thin, and the whole object is smaller.

Cybex figures from CYBEX — Libelle product page (folded and unfolded dimensions, weight, capacity), read 2026-10-14, corroborated by the retail listing in our registry read 2026-09-27. Stokke figures from Stokke — YOYO FAQ (folded dimensions), read 2026-09-27. The volume figures are our own arithmetic on the brands' published dimensions and are rounded; treat them as a comparison rather than a specification. The YOYO was formerly sold as the BABYZEN YOYO.
The arithmetic that decides it
Multiply the three published numbers out. The Libelle folds to about 1,860 cubic inches. The YOYO folds to about 2,500. That is roughly a third more stroller to find room for, in exchange for 0.7 in less thickness.
Whether that trade is good depends entirely on which constraint you hit. A shallow overhead bin is a depth constraint: the hinge-to-back dimension is the thing that is short, and 7.1 in goes in where 7.8 in has to be forced. A packed car trunk, a hotel wardrobe or the inside of a checked suitcase is a volume constraint, and there the 20.5 in length of the YOYO is the problem rather than its thickness.
The newborn question splits them cleanly
Cybex publishes a 6-month start for the Libelle. That is not a soft recommendation; it is the brand’s stated suitability, and it means the Libelle cannot be your first stroller unless you also own an infant car seat and a way to carry it.
The YOYO is configurable from birth. If you are buying before the baby arrives, that difference matters more than anything else on this page, and it is worth the extra third of a cubic foot. If you are buying for a one-year-old who already walks half the time, it is irrelevant. Our travel strollers for infants roundup ranks the whole registry on the published lower limit, which is the spec almost no compact brand states.
The weights are a tie, and that is useful to know
Cybex publishes 13.7 lb. Stokke publishes “from 13.6 lb depending on configuration”. A tenth of a pound is not a reason to choose anything, and the phrase “depending on configuration” is a reminder that the YOYO is a system with options rather than a single object.
So weight is off the table, which is unusual in this category and genuinely simplifies the decision down to shape. Both are also far inside the only hard airline weight rule we have found — American publishes that a fully collapsible stroller may be carried on if it is under 20 lb and it fits in an overhead bin, and is otherwise gate-checked free when traveling with a child (aa.com, read 2026-09-27).
What we’d skip
Choosing on “folds smallest” claims. Both brands make one. They are both true and they mean different things. The only way through is the three published numbers, which is why this page is a table.
Assuming either is guaranteed in the bin. Bin depth varies by aircraft, and neither brand names an airline. Plan for a gate check and be pleased when you get a bin — our gate-checking guide covers doing that without damage, and gate checking a stroller and car seat sets out what each airline publishes about the allowance.
Choose the Cybex Libelle if
- You need the smallest total package — about 1,860 cubic inches folded
- It has to go inside a checked suitcase, a packed trunk or a hotel wardrobe
- You want a published maximum child weight, which Cybex gives as 22 kg
- Your child is already 6 months or older
- You would rather have one published weight figure than a range
Choose the Stokke YOYO if
- The overhead bin is the constraint and 7.1 in of depth is the reason
- You are buying before the baby arrives and need a newborn configuration
- A shoulder strap matters because you will carry it down an aisle
- You accept about a third more folded volume to get the thinner profile
- You are happy to confirm the weight limit with the retailer before buying
The verdict
Cybex Libelle for most buyers. It is the smaller object, it publishes the capacity figure, and “fits inside a checked suitcase” solves a problem that a thin fold does not.
Stokke YOYO if you fly constantly and have been handed a gate-check tag one time too many, or if you need a stroller from birth. The 7.1 in is real and it is the only number on this page that can turn a gate check into a bin.
Both sit in our travel stroller roundup, the YOYO has its own page at the YOYO review, and if neither fold convinces you, YOYO vs UPPAbaby MINU is the capacity argument instead.
The Libelle’s other close rival is the one that answers the question this page cannot: the Joolz Aer2 is usable from birth as sold, where the Libelle’s seat starts at 6 months. Our Cybex Libelle 2 vs Joolz Aer2 comparison has the packed-volume arithmetic on both.

Cybex Libelle 2
Folds to 12.6 x 7.8 x 18.9 in (200 x 320 x 480 mm) at 13.7 lb (5.9 kg), for children from 6 months to a maximum 22 kg, and it is small enough folded to fit inside a checked suitcase.
Best for: A bin, a car trunk, or the inside of a checked suitcase
| Folded | 12.6 x 7.8 x 18.9 in (32 x 20 x 48 cm) |
|---|---|
| Weight | 13.7 lb |
| Air travel | listed as carry-on compliant for most airlines; fits inside a checked suitcase |
Specs from Cybex Libelle 2 listing with folded dimensions, read 2026-09-27. Manufacturers revise specs without notice — check the listing before you buy.
Good at
- 12.6 x 7.8 x 18.9 in folded — the smallest overall folded package in our registry by volume
- 13.7 lb (5.9 kg), published by Cybex as the same figure folded or unfolded
- Published maximum child weight of 22 kg, which the Stokke FAQ we read does not give at all
- Unfolded 710 x 520 x 1020 mm, so it is a full-size footprint from a tiny fold
- Fits inside a checked suitcase — no other stroller in our registry is described that way
- Listed as carry-on compliant for most airlines
Bad at
7.8 in of folded depth is 0.7 in thicker than the YOYO, and depth is the dimension an overhead bin is short of — in a full bin that 0.7 in is the whole argument against it. Cybex also publishes a 6-month start, so it is no use at all for a newborn without a separate infant seat, where the YOYO has a newborn configuration.

Stokke YOYO³ (formerly BABYZEN YOYO)
Folds to 20.5 x 17.3 x 7.1 in (52 x 44 x 18 cm) from 13.6 lb depending on configuration, with a shoulder strap and a folding handlebar, and Stokke states the fold meets most airlines' cabin baggage allowance.

|---|---|
| Weight | from 13.6 lb depending on configuration |

Specs from Stokke YOYO FAQ — folded dimensions, read 2026-09-27. Manufacturers revise specs without notice — check the listing before you buy.
Good at
- 7.1 in of folded depth — the thinnest published fold on this site
- From 13.6 lb depending on configuration, marginally lighter than the Libelle
- Shoulder strap included, so it is carried rather than dragged
- Folding faux-leather handlebar — the mechanism that produces the 7.1 in
- Stokke states the fold meets most airlines' cabin baggage allowance
- Configurable from birth, which the Libelle's published 6-month start rules out
Bad at
It is thinner and bigger. At 20.5 x 17.3 x 7.1 in it is roughly 2,500 cubic inches against the Libelle's roughly 1,860 — about a third more volume — so it wins a shallow bin and loses a packed trunk. Stokke's FAQ page also publishes no maximum child weight, and "from 13.6 lb depending on configuration" means the weight you get depends on what you buy.

UPPAbaby MINU V3
16.7 lb, folded 10 x 18 x 21.5 in, suits 0-50 lb, folds one-handed in one motion, and UPPAbaby states it is IATA compatible and fits an overhead compartment.
Best for: A published 50 lb ceiling and a fold you can do one-handed
| Folded | 10 x 18 x 21.5 in (L x W x H) |
|---|---|
| Weight | 16.7 lb |
| Suits | 0-50 lb |
| Air travel | IATA compatible; the brand states it fits an overhead compartment |
| Fold | one-handed, one motion |
Specs from UPPAbaby MINU product page, read 2026-09-27. Manufacturers revise specs without notice — check the listing before you buy.
Good at
- 0-50 lb published capacity — the highest published ceiling of the three
- One-handed, one-motion fold, which neither of the other two offers
- UPPAbaby states it is IATA compatible and fits an overhead compartment
- A single published weight figure rather than a range
Bad at
16.7 lb is the heaviest here by 3 lb, and 10 in of folded depth is the thickest of the three — it loses both of the arguments this page is about. It is on this page as the alternative for someone who has decided that capacity and a one-handed fold matter more than packing small.

Questions parents actually ask
Is the Cybex Libelle or the Stokke YOYO better?
The Libelle if the stroller has to fit in a confined space overall, the YOYO if it has to slide into a shallow overhead bin. Cybex publishes a folded size of 12.6 x 7.8 x 18.9 in, which is roughly 1,860 cubic inches. Stokke publishes 20.5 x 17.3 x 7.1 in, which is roughly 2,500. The YOYO is thinner by 0.7 in and bigger by about a third.
Which one fits in an overhead bin?
Both brands claim the cabin in their own words: Cybex's Libelle is listed as carry-on compliant for most airlines, and Stokke states the YOYO fold meets most airlines' cabin baggage allowance. Neither is a guarantee on your specific aircraft. If the bin is shallow, the deciding figure is depth, and that is 7.1 in for the YOYO against 7.8 in for the Libelle.
What is the weight limit on each?
Cybex publishes a maximum child weight of 22 kg for the Libelle, which is about 48.5 lb, with a suitability range from 6 months to approximately 4 years. Stokke's YOYO FAQ page — the page where the folded dimensions are published — gives no maximum child weight, and we are not going to supply one from a retailer and present it as the brand's.
Can you use either from birth?
The YOYO, yes, in a newborn configuration. The Libelle, no — Cybex publishes a 6-month start, so a newborn needs a separate infant car seat on a frame or a carrier instead. If birth-to-toddler out of one purchase is the brief, read our travel strollers for infants roundup, which ranks on the published lower limit rather than the folded size.
Which is lighter?
They are within a tenth of a pound of each other on paper. Cybex publishes 13.7 lb (5.9 kg) for the Libelle. Stokke publishes the YOYO as from 13.6 lb depending on configuration — which means the figure you actually get depends on which version you buy. Treat them as the same weight and decide on something else.
Does either count as a carry-on with the airline?
That is the airline's call, not the brand's. American publishes the clearest rule we have read: a fully collapsible stroller may be carried on if it is under 20 lb and it fits in an overhead bin, otherwise it is gate-checked free when traveling with a child. Both of these are far under 20 lb, so the bin is the live question — our carry-on stroller size guide lines the folded figures up against what each airline publishes.
