SizeShelfKids' clothes size inventory

SizeShelf is a kids' clothes inventory for parents who keep outgrown and too-big clothes in bins sorted by size. You add a child with a birth month and the size they wear now, and a card estimates roughly when the next size will be needed and shows how many pieces in that size you already have. Every piece is filed by size, category, season and the bin it lives in, and clothes passed to a younger sibling move onto that child's shelf. It all stays on your phone, with no account.

Three moments

01

See the next-size gap before it arrives

Add a child with a birth month, the size they wear now and one answer: how many pieces in the next size do you already have? The card lights up on the spot, for example 3T in about six months, with nothing on the shelf yet. The timing comes from published growth charts and is always a rough range, shown next to a note that every child grows differently.

02

File every piece by size, season and bin

The Shelf puts last size, this size and next size side by side, each with a plain count. Inside a size you see tops, bottoms, outerwear and underwear, and every piece carries the bin it lives in, such as Dresser, drawer 2 or Hall closet bin. Finding the 2T rain jacket takes three taps: size, category, bin.

03

Pass outgrown clothes on and keep the record

Mark outgrown pieces as passed on, with who received them, the date and a note. When the receiver is a younger sibling in the app, the clothes move onto that child's shelf in the same size and count toward their next size. Bags that come in from cousins and friends are logged with who they came from.

Bins, labels and a running count in your head

Most families with young kids store clothes the same way. A dresser holds what fits now, and a stack of bins in a closet, the garage or under a bed holds everything else. The bins get labels like 18M or 3T winter, and the real inventory lives in one parent's memory.

That works until it does not. A cold week arrives right after a growth spurt and the 3T coat is not where you thought. A cousin drops off two bags of hand-me-downs and they sit unsorted for a month. You find nine 2T pajama sets and no 3T pants at all. A notes list or a spreadsheet helps for a while, but neither one knows which size your child is about to grow into.

How the next-size estimate works

SizeShelf asks for very little: the child's birth month, the size they wear now and, if you have noticed it, whether they tend to grow faster or slower than most. From that it reads published child growth charts and places the next size as a range of time, such as in about 6 months. It does not invent its own growth formula, and it never shows a single exact date. For ages the charts do not cover, the card says it has no estimate instead of guessing.

The estimate is then set against what is on the shelf in that size, category by category. Zero pieces shows as none, one or two as low, three or more as ready. If the next size is likely to arrive in winter and there is no coat in that size, that gap is listed first. Tap a short category to jump straight to that size on the Shelf.

Reminders are optional. Turn them on, choose how many weeks ahead you want to hear, and the phone will tell you when it is time to check the next size. The lock screen text is one neutral line for everyone and never shows a child's name, a size or anything about growth.

Putting a closet in, one bin at a time

The usual way in is sitting on the floor next to an open bin. Each piece gets a size, a category (tops, bottoms, outerwear, underwear, shoes or other), a season (spring and fall, summer, winter or all year), the bin it goes back into and a quantity. A photo and a note are optional, and skipping the photo is the fast path, not a fallback.

After you save, the last size, category and bin stay filled in, so ten 2T tops from the same drawer take ten short entries instead of ten blank forms. Each piece can also say where it came from: purchased, handed down or a gift.

Before another pack of 2T leggings comes home, filter the Shelf to 2T and bottoms. The count is right there, along with the bins they are in.

Sizes the way your labels print them

In the US that means month sizes such as 0-3M and 18M, then toddler sizes 2T, 3T and 4T, then kids' sizes 5, 6 and up. SizeShelf also knows the centimeter-based sizes used in Europe and Japan and the numbered sizes used in Korea, and you choose the system in Settings.

When a piece carries a label from another system, the app shows an approximate match, such as 90 ≈ 2T, with a reminder that brands cut differently. Where there is no sensible match it shows none, rather than forcing one.

Hand-me-downs, in both directions

Kids' clothes rarely have one owner. They come in from cousins, neighbors and friends, and they go out again to a younger sibling or another family. The hand-me-down ledger keeps both sides: what went to whom and when, grouped by person, and what came in from whom.

When a child sizes up, you confirm the new size and the old size's pieces are offered for sorting. Select a batch and choose pass down, keep as a keepsake, or let go, and the Shelf and the next-size card update together. Passing to a younger sibling who is already in SizeShelf moves the clothes to that child's shelf, so an older child's 3T bin becomes a younger child's next size.

None of this asks for more than a record. There are no thank-you reminders, no share cards and no social features, and receivers are typed in by hand, so the app never asks for your contacts. Every entry can be edited, and undoing a hand-off puts the pieces back on the shelf they came from.

What SizeShelf leaves out

SizeShelf is an inventory, not a growth tracker. It does not record height or weight, plot percentiles or comment on how a child is growing. It is not a catalog either: there are no product links, no resale listings and no suggestions about what to get next.

There is no account and no server. The app makes no network requests and asks for two permissions only: photos, when you add a picture to a piece, and notifications, when you turn reminders on. Saying no to either changes nothing else. Photos are copied into the app's own storage. You can export everything except the photos to a JSON file through the share sheet and restore it on a new phone, and Settings has one option that deletes all data, photos and scheduled reminders included.

Frequently asked questions

How does SizeShelf know when my child will need the next size?

It does not know; it estimates. From the child's age in months, current size and an optional faster or slower setting, it reads published growth charts and gives a time range such as in about 6 months. Children grow at different rates and brands cut differently, so treat it as a nudge to check the bins, not a date.

Does it track my child's height or weight?

No. SizeShelf never asks for height or weight and has no growth charts to fill in. The only inputs are birth month, current size and the optional growth pace. For anything about growth itself, talk to your pediatrician.

Can I use US sizes like 0-3M, 2T and 3T?

Yes. US month, toddler and kids' sizes are one of the built-in systems, alongside centimeter-based European and Japanese sizes and Korean sizes. Pick the system in Settings; a piece labeled in another system shows an approximate match marked with ≈.

Can I pass clothes from an older child to a younger one?

Yes. Choose the pieces, pick the younger sibling as the receiver and confirm. The clothes move to that child's shelf in the same size, count toward their next-size card when that size is coming up, and the hand-off is recorded in the ledger. You can undo it later.

Where is my children's information stored?

Only on your phone. There is no account, and SizeShelf makes no network requests. A child's name is optional, and a nickname works. Photos stay in the app's own storage, and reminders on the lock screen use one neutral line with no names or sizes.

How do I move everything to a new phone?

Export a JSON backup through the share sheet, keep the file wherever you like, and restore it on the new phone. The backup carries every child, piece and ledger entry, but not the photos, and the export screen says so.
