Kids Bed Sizes by Age: Chart From 60×120 to 140×200

Up to about 3 years, your child sleeps well in a 60×120 cot. After that, 90×200 is the safest choice among all kids bed sizes: it fits from the second birthday and lasts into the teenage years. Smaller sizes such as 70×140 or 80×160 only make sense when the room is really tight – most children outgrow them by preschool age.

Which kids bed size fits which age?

The chart shows when and for roughly how long each size fits. It is a guide: tall children need more length sooner.

Bed size	Fits roughly	Good to know
60×120	0–3 years	cot, adjustable base
70×140	1–4 years	toddler bed, often short early
80×160	1.5–5 years	only if space is very tight
80×180 / 90×180	2–8 years	in-between size
90×190	2–12 years	short single
90×200	2 years into the teens	standard, most popular
120×200	2 years, for many years	wide, room for stories
140×200	from 2 years	with us only as Mini, on the floor

A bed does not become too small because your child gets older, but because they get taller. Around 5, many children are about 110 cm tall; at 10, about 140 cm. Add 20–30 cm and you see why a 160 cm bed gets tight in the school years and a 200 cm bed does not.

60×120 cot: how long does it really fit?

The 60×120 cot is the standard size for the first years. An adjustable base grows with your baby: high for the newborn, at the bottom once your child pulls up to stand. Our VERA cot bed has three base heights and, according to its product description, is designed for children up to about 3 years.

Usually, though, climbing is the problem, not length. Once your child gets over the rail, it is time for a bed with a low entry, often between the second and third birthday. Our guide bed for a 2 year old explains how to spot the right moment.

70×140 or 80×160: is a toddler bed worth it?

The classic toddler bed size is 70×140; 80×160 is a common alternative. Both suit a small child and save room, but by four or five they are often too short. Then you need a second bed, mattress and bedding – you buy twice.

A small size makes sense in three cases:

• The room is really small and every centimetre counts.
• The bed is a second bed, for example at the grandparents’.
• You are planning a bunk or loft bed anyway as soon as your child turns 6.

Otherwise, a bigger bed is not “too big”. With a fall guard, even a two-year-old feels snug in it.

90×190 or 90×200: which size is better?

Both sizes last for many years. 90×200 is the standard size – mattresses, fitted sheets and bedding are easy to find, and families choose it most often in our shop.

90×190 saves 10 cm in length. That helps when the bed has to fit between a door and a wall. Our TEO Montessori bed, for example, only comes in 90×190 – with outer dimensions of 197 x 97 cm it fits into small rooms too.

In-between sizes such as 80×180 or 90×180 are a compromise for tight alcoves. With our house beds such as the LUMINA children’s bed, you choose from seven sizes between 80×160 and 120×200. Every bed is made of pine wood and handmade in Europe.

120×200 and 140×200: when is a wide kids bed worth it?

A wide bed is not a luxury if you often lie down with your child at bedtime. 120×200 gives your child plenty of room and stays a comfortable bed into the teenage years. The frames of our house beds carry up to 190 kg – enough for a child and a parent.

140×200 is only available as a mini version directly on the floor, for example the LUMINA mini house bed. That is practical if a parent often stays until the child falls asleep. Who this size really suits is explained in our guide floor bed 140×200 for kids.

How much room does the bed need in the children’s room?

The bed size is the sleeping surface, not the whole bed. The frame usually adds about 7–10 cm in length and width – exact outer dimensions are on every product page.

• In front of the bed you need about 60–70 cm of free floor for climbing in and making the bed.
• With a drawer bed, add the length of the drawer when it is pulled out.
• With a house bed with a roof, height counts too – important under a sloping ceiling.

Tip: mark the outer dimensions on the floor with masking tape to check the door, wardrobe and play corner.

Which mattress and bedding fit which size?

The mattress always has exactly the size of the sleeping surface: a 90×200 bed takes a 90×200 mattress. It must lie in the frame without a gap, so arms or legs cannot get caught, and be firm – a soft adult mattress gives too much under a light body. You will find matching sizes among our children’s mattresses.

Bed size	Mattress	Bedding (duvet)
60×120	60×120	100×135 or smaller
80×160 – 90×190	same as the bed	100×135
90×200 – 140×200	same as the bed	140×200, pillow 50×70

Children’s duvet and pillow sets in these sizes are in our bedding range.

From what age is a bunk bed or loft bed suitable?

For the top bed, age counts, not size: only from 6 years, as required by the European standard EN 747 for bunk and loft beds. Ireland’s health service gives the same advice and adds that bunk beds should stand away from windows (HSE: preventing falls). Our bunk beds have standard sleeping surfaces; the exact measurements are on every product page. A younger sibling can sleep in the bottom bed earlier.

The 5 most common mistakes when choosing a bed size

These mistakes come up again and again – and are easy to avoid:

1. Buying for today’s age instead of the next few years. A bed often lasts ten years or more – will it still fit at 8 or 10?
2. Measuring only the sleeping surface. The frame, roof, drawer and the free floor in front of the bed all need extra space.
3. Choosing an unusual size without thinking of mattress and bedding. For 90×200 you will find everything everywhere; for rare sizes every fitted sheet becomes a search.
4. Reusing an old mattress that does not fit exactly. A gap between mattress and frame is uncomfortable and can be dangerous.
5. Moving to a loft bed too early. Even if the size fits: children sleep up top only from 6 years.

Conclusion: choose right once instead of buying twice

For the first years, a 60×120 cot is enough. For the first big bed, 90×200 is the size that lasts longest – or 90×190 if the room is tight. If you like to lie down with your child, go for 120×200 or, on the floor, 140×200. Add a firm, snug mattress and free space in front of the bed.
