Help & Support

Sizewise remembers your size in every brand, so you never have to guess in the shop. This guide explains how it works and how to get set up.

The big picture

Sizes differ between brands, regions and categories. Sizewise is a small, calm place to keep yours.

Save a size once, find it in a second. You pick a brand, a category (tops, shoes and so on) and your size. Later you search the brand and it is right there.

Add a fit note if a brand runs small or large, and share a size as a garment-label card when someone asks.

Everything stays with you. There is no account, no tracking and nothing to sign in to. What you enter is stored on your iPhone and never sent to us. With Plus you can also keep your sizes in sync through your own iCloud.

Core concepts

A handful of building blocks. Most people only ever need the first three.

Who

People

Sizes belong to a person. Sizewise starts with You. When there is more than one person, a switcher appears on the Sizes screen so you can flip between them.

Free includes one person. Plus lets you add more.

In the app: Me tab

Where

Brands

Start typing a brand and Sizewise suggests known ones. If yours is not there, type it and it is added as your own brand on this device.

In the app: Sizes tab → +

What

Sizes and categories

A saved size is a person's size in one brand and one category: tops, bottoms, shoes, outerwear, underwear or accessories. Pick a size system (EU, US, UK, JP or CN) and choose a quick size or type your own.

In the app: Sizes tab → +

Your own groups

Sub-categories

Need more detail than a category? Make your own sub-categories, like Hat or Jeans, with an icon. Your sizes can sit under them. Deleting a sub-category keeps the sizes.

In the app: Settings → Categories

How it fits

Fit notes

Mark a size as runs small, true to size or runs large. Flag where it is off: shoulders, chest, waist, hips, length, sleeves, width or toe box. Add a private note for anything else.

The private note is only for you and is never part of the shared label.

In the app: Open a size → Fit

Your body

Measurements

Keep chest, waist, hips, inseam and foot length in centimeters or inches. Each one comes with a short how-to-measure guide. Sizewise stores your numbers and does not recommend sizes.

Measurement history is part of Plus.

In the app: Me tab → Measurements

Show it off

Size label

Every size is shown as a woven garment label. Share it as an image from the size's detail screen, or press and hold a row on the Sizes screen.

In the app: Open a size → Share

Common setups

Step-by-step guides for things people often do first.

Save your first size

You are in a shop and want to remember your size for next time.

  1. On the Sizes tab, tap + (or Add your first size).
  2. Type the brand and pick a suggestion, or keep what you typed.
  3. Choose a category, then a size. Tap Other unit to switch size system, or type your own size.
  4. Optionally set the fit, then tap Save size.

Look up a size in the shop

Which size was it in that brand again?

  1. Open the Sizes tab and type the brand in Which brand?
  2. Tap the result to see the size large, with its fit note.
  3. Prefer browsing? Switch between By category and By brand, and between grid and list.

Add a fit note

The jacket is a size M, but the sleeves are short.

  1. Open the size from the Sizes tab.
  2. Under Fit, choose Runs small, True to size or Runs large.
  3. Tap the areas that are off, like Sleeves.
  4. Write anything else in the Private note. Only you see it.

Switch units

You shop across regions, or prefer inches.

  1. Go to Settings → Units.
  2. Choose your default size system (EU, US, UK, JP or CN) and measurement unit (cm or in).
  3. New sizes and measurements start with these. You can still pick another size system for a single size when you add it.

Share a size label

A friend asks what size you wear.

  1. Open the size you want to share.
  2. Tap Share label and pick where to send it.
  3. The label shows the brand, category, size and fit. Your private note is never included.

Take your measurements

Useful when a brand's size chart is in centimeters.

  1. Open Me → Measurements.
  2. Tap a measurement, such as Chest, and read the short how-to guide.
  3. Enter the value, choosing cm or in.

Coming later. A widget, an Apple Watch app and Siri shortcuts are planned, and are not in the app yet.

iCloud sync (Plus)

With Plus, your sizes stay up to date on every device signed in to the same iCloud account. They live in your own private iCloud. We never see them.

Turn sync on or off

Sync is on by default for Plus.

  1. Open Settings → iCloud and use the iCloud sync switch.
  2. Reopen Sizewise to apply the change.
  3. The status row under the switch shows whether you are up to date, syncing, waiting for a connection, or need to sign in to iCloud.

New device, reinstall, or your first time using iCloud

Sizes may already exist in iCloud and on this device.

  1. If only one side has sizes, Sizewise simply starts syncing. Nothing is lost.
  2. If both iCloud and this device have sizes, Sizewise asks which to keep. You see what each copy holds.
  3. Choose Keep iCloud or Keep this device, then confirm. The copy you do not choose is overwritten and cannot be recovered, on all your devices.
  4. Not sure yet? Tap Not now. Nothing changes, sync stays off, and Sizewise asks again the next time you open it.

Turning sync off and on again, or signing in with a different Apple ID, brings the question back.

If sync does not start

  1. Make sure you are signed in to iCloud in the iOS Settings app and that iCloud has free space.
  2. Check that Low Power Mode is off and that you are online.
  3. Reopen Sizewise. If you were signed out or offline at launch, it checks again the next time it opens.

Reading the main screens

Three tabs along the bottom. Here is what lives where.

Sizes

Your saved sizes. Search by brand at the top, switch By category or By brand, and flip between grid and list with the button in the corner. Tap + to add a size. Searching always shows a list of results.

Size detail

Opens when you tap a size. It shows the label, who it is for, and when you last used it. From here you can share the label, set the fit, edit the size or delete it.

Me

Your people and your body measurements. Adding more people needs Plus.

Settings

Units for size system and measurements, Categories for your own sub-categories, Sizewise Plus and restoring purchases, iCloud sync for Plus, a link to this Help page, and the Privacy Policy and Terms of Use.
