One brand, one design language, two crib sizes. Because everything else is held constant, this is the cleanest way to answer the question people are actually asking: mini crib or full-size?

Buy the Hudson unless your room genuinely cannot take it. A full-size crib is the default for a reason: it uses a standard mattress you can replace anywhere, the baby will not outgrow it, and it costs less per year of use. Buy the Gelato when the room is under roughly 8 by 8 feet, or when the crib shares a bedroom — at 26 inches wide and about 39.75 inches long, it gives back real floor. The surprise is that the Gelato converts further than the Hudson does: Gelato to a mini toddler bed to a twin, while the Hudson stops at a toddler bed and daybed with no full-size path.
Scope, per how we pick: these are the dimensions, conversion paths and certifications Babyletto publishes, as recorded in our catalog. We have not assembled both cribs. Every crib sold in the US, mini or full-size, must meet a mandatory federal safety standard, so this comparison is about size, cost and longevity — not about one being safer than the other.

The mattress is the hidden cost, and it is a safety point
Neither crib includes a mattress, and this is where the mini-crib decision stops being about inches. A mini crib needs a minicrib mattress — the Gelato's interior sleep area is 37 by 24 inches, so you want a mattress sold as roughly 38 by 24. A standard full-size crib mattress is about 52 by 28 inches and will not fit.
Mini mattresses are a smaller market, which means less choice and, pound for pound, often a worse price than the full-size equivalent. The Hudson takes a standard mattress you can buy from anyone, including every pick in our crib mattress roundup. That is a real advantage of full-size that nobody puts on a spec sheet.
How long each one actually lasts
This is the part that surprises people, because it runs opposite to the intuition that bigger lasts longer.
As a crib, the Hudson lasts longer: a full-size crib holds a child until they climb out or reach the height limit, typically somewhere around two to three years, while a mini crib is tighter from the start and some babies look cramped in one by 18 months. If your only question is “how long until I need another bed,” full-size wins.
As a piece of furniture, the Gelato lasts longer: its conversion path runs mini crib to mini toddler bed to twin bed, so the frame becomes a bed a school-age child sleeps in. The Hudson converts to a toddler bed and a daybed and stops — there is no full-size conversion. Both brands sell the kits separately, which is the recurring Babyletto footnote: the sticker price is not the lifetime price.
The third option, if you want a mini crib without the homework
The DaVinci Otto 3-in-1 mini crib solves the mattress problem by including a genuine 4-inch mini mattress, so the box you open is the whole sleep setup. It also has the smallest published footprint of the mini cribs we list, at 38.5 by 25.5 inches, and DaVinci publishes a 135 lb slat strength and a 45 lb child limit.
What you give up: it does not fold or roll, it is the heaviest mini crib we list at about 51.5 lb assembled, and its conversion stops at a mini toddler bed and daybed — no twin path. So the choice between the two minis is simple. Otto if you want one purchase and are done; Gelato if you want the frame to become a twin bed later and do not mind buying a mattress and two kits along the way. Our mini crib roundup has all six with their published footprints, and nursery furniture for small spaces puts a mini crib into a whole room and does the floor-space arithmetic.
If you have decided on full-size and are choosing between looks rather than sizes, Hudson vs DaVinci Kalaniis the comparison to read next — the Kalani converts all the way to a full-size bed, which is the Hudson's one real weakness. The wider field is in best cribs.
The mini crib that behaves most like a real crib — four mattress heights, a 26-inch-wide footprint, and a conversion path that runs all the way to a twin bed.

What we like
Four mattress heights — the most of any mini crib here, so it stays usable once the baby can sit and pull up
Converts to a mini toddler bed and then a twin, so the frame isn't a throwaway
Only 26 inches wide, and GREENGUARD Gold certified
Worth noting
No mattress in the box — you get a waterproof pad, which is not a sleep surface on its own
Both conversion kits are sold separately, so the long-term cost is higher than the sticker
Doesn't fold or roll, and it's the priciest pick here
The rare mini crib that ships with a real 4-inch mattress instead of a thin pad, so the box you open is the whole sleep setup.

Frequently asked questions
Is a mini crib worth it instead of a full-size crib?+
In a room under about 8 by 8 feet, or a shared bedroom, yes — the Gelato is 26 inches wide and about 39.75 long against a full-size crib's roughly 28 to 30 by 54. In a normal-size room, a full-size crib is the better buy: it uses a standard mattress you can replace anywhere, and the baby will not outgrow it as early.
Which lasts longer, the Babyletto Gelato or the Hudson?+
It depends what you mean. As a crib the Hudson lasts longer, because a full-size crib stays comfortable until the child climbs out or hits the height limit while a mini can look cramped by around 18 months. As furniture the Gelato lasts longer: it converts to a mini toddler bed and then a twin, while the Hudson stops at a toddler bed and daybed with no full-size path.
Does the Babyletto Gelato come with a mattress?+
No. It ships with a waterproof pad, which is a cover and not a sleep surface — do not use it as the mattress. You need a mini crib mattress sized for its 37 by 24 inch interior sleep area, usually sold as 38 by 24 inches. A standard full-size crib mattress, about 52 by 28, will not fit.
Are mini cribs as safe as full-size cribs?+
Yes, when used correctly. Full-size and non-full-size cribs are each covered by their own mandatory federal safety standard, so neither size is inherently safer. What matters in both is the same: a snug mattress fit with no gap wider than about two fingers, a firm flat surface with nothing else in the crib, the baby on their back, and the mattress dropped to its lowest setting before the baby can pull to stand.
Can I use a regular crib mattress in a mini crib?+
No. A full-size crib mattress is about 52 by 28 inches and a mini crib's interior sleep area is about 37 by 24. Forcing an oversized mattress in, or accepting an undersized one, leaves gaps at the edges — exactly the hazard safe-sleep guidance exists to prevent. If you want to avoid the extra purchase entirely, the DaVinci Otto mini crib includes a correctly sized 4-inch mattress.
