Quick answer: Under two, storage is for adults and should be out of reach. From about two to five, everything a child uses should be open, low and unsorted. From six upwards they can manage simple categories and labels, so storage can become a system rather than one big basket.
Three children at three different stages taught me that the storage that works brilliantly one year is useless the next.
Babies and under-twos: storage is for you
At this stage the child is not putting anything away, so storage is entirely about the adult finding things quickly, often one-handed.
What helps: shallow open baskets at changing height so you can see everything without looking, one category per basket, and nothing that needs two hands to open.
Keep anything a baby should not reach genuinely out of reach rather than merely lidded. Check the manufacturer's own age guidance and safety information for any item, since that varies by product - the nursery and kids range is where to look.

Two to five: open, low, and one big basket
The stage where children start tidying, and where most storage systems get it wrong.
A toddler will do "put it in the basket". They will not do "decide which of these six boxes this belongs in", because that is a sorting task and they are not sorting yet.
So: one large open basket for toys, at floor level, in the room the toys are actually used - the toy basket guide covers why bigger and simpler wins.
Soft-sided baskets suit this age, since they have no hard corners and weigh nothing when pulled over. Nothing with a heavy lid.
Five to seven: two or three categories
Now sorting becomes possible, but only coarsely.
Two or three obvious categories is about the limit - big toys, small toys, books. Pictures on labels work better than words at this stage, and a photograph of the contents works better than a drawing.
Keep everything low enough for them to reach without help. If an adult has to lift it down, the adult is doing the tidying.
This is also the age where a basket per child starts to matter, because ownership disputes become a daily feature.
Eight and up: a real system
From here a child can manage labelled categories, remember where things live, and take responsibility for their own room.
Storage can become finer - craft supplies separated, Lego by colour if that is their thing, schoolwork in its own place. Small baskets and drawer dividers start to earn their place - the small baskets guide covers dividing space.
Let them arrange it. A system a child designed gets maintained; one imposed on them does not, however sensible it is.
Teenagers
Storage stops being about toys and becomes about clothes, technology and school things.
Under-bed storage comes into its own, because bedrooms get smaller relative to the amount of stuff - under-bed boxes handle the seasonal clothes and the things they will not throw away.
Accept less control. A closed door and adequate storage is a better deal than a daily argument.
What carries across every age
Open beats lidded for anything in daily use. A lid is a step, and children have less patience for steps than adults.
Low beats high. If they cannot reach it, you are the storage system.
In the room the things are used, not the room you would prefer.
Fewer, bigger containers until they are old enough to sort.
The toy storage guide covers building the whole thing.
Rotation works at every age
The one technique that helps from about eighteen months to eleven.
Most children play with a fraction of what they own. Putting some away in a lidded box and swapping every few weeks reduces the volume out at once and makes old things feel new - the toy storage guide covers doing it.
It also makes the daily tidy-up genuinely quicker, which is the part you feel.
Buying for a stage they are leaving
The most common waste of money.
A four-year-old will not be four for long, so buying a heavily themed or age-specific storage unit rarely pays. Plain baskets in neutral or simple colours carry from toddler to teenager and can move to another room afterwards.
Getting them to use it
The storage is the easy part; the habit is not.
Two things work at almost every age. Make tidying a fixed part of the day rather than a response to mess, so it is not a punishment. And make it achievable - a five-minute tidy with a timer beats "tidy your room", which is an unbounded task that produces paralysis.
Doing it alongside them works far better than instructing from a doorway, particularly under about seven.
Sharing a room
Where siblings share, ownership disputes cause more mess than volume does.
One basket each, clearly theirs, plus shared baskets for genuinely communal things. Different colours or a name label makes it unambiguous, and it removes an entire category of argument.
Keep the shared baskets in the middle and the personal ones by each bed - the styling and care guide covers keeping that from looking chaotic.

The short version
- Under two, storage is for the adult - shallow, open, one-handed, and out of reach where needed.
- Two to five: one large open basket, floor level, in the room the toys are used.
- Five to seven: two or three coarse categories, with picture labels rather than words.
- Eight and up can manage a real system - and will maintain one they designed themselves.
- Buy plain rather than themed; a four-year-old is not four for long.
Frequently asked questions
What storage works for a toddler?
One large open basket at floor level in the room the toys are actually used. A toddler will put things in a basket but will not decide which of six boxes something belongs in, because that is a sorting task they cannot do yet.
When can children start sorting their own toys?
Around five to seven, and only coarsely - two or three obvious categories such as big toys, small toys and books. Picture labels work better than words at that stage, and photographs work better than drawings.
How should storage change for older children?
From about eight they can manage labelled categories and finer division, so small baskets and drawer dividers start to earn their place. Let them arrange it, because a system a child designed is one they will maintain.
Should children's storage have lids?
Not for anything in daily use. A lid is an extra step and children have less patience for steps than adults, so lidded toy boxes tend to end up with the toys beside them. Save lids for rotation and seasonal storage.
Is themed children's storage worth buying?
Rarely. A four-year-old will not be four for long, so heavily themed units get outgrown quickly. Plain baskets in neutral or simple colours carry from toddler to teenager and can move to another room afterwards.
