# One of our items runs small or large. Can the size advice recommend a size bigger or smaller for it?
## The question
- One of our items runs small, and the size advice recommends the size shoppers normally wear (for example M, where it should be L). Can it recommend one size bigger for this item?
- Does this have to be set for every size and colour, or once for the whole product? Can it be set for only some sizes, for example C42 to C48?
- If we set a product's True to Size to `-1`, are shoppers advised one size bigger? What is a whole size, and what is a half?
- Can the size advice recommend one size larger across all our products?
- We have a list of items that run smaller or larger. Can you adjust the size advice for them?
## Applies to
- A shop with the Faslet widget on its product pages; any shop platform
## Answer
Yes. Each product can get a True to Size value that says how it fits, and the size advice for that product then moves a size up or down. It counts for the whole product: every size moves (M becomes L, L becomes XL), for all colours that are one product in your shop; it cannot be set for some sizes only. It counts only for your shop.
You can set it yourself, or we set it for you.
**Yourself**, in the Faslet portal, if your store has True to Size in its Products screen (not every store does): open [Products](https://portal.faslet.net/products), pick your store at the top, open the product, and set its True to Size (the values are in the table below). Click the **save** in its True To Size block, and the size advice for that product changes with it. Don't see True to Size in the product, or does saving give an error? Then send us the products as below.
**We set it for you:**
1. Send us the products (links or product numbers) and how each one fits: for example "runs a size small", "runs half a size large". A list is fine, also a long one; in a spreadsheet, check that the product numbers show in full, not as something like `1.56E+18`. Return figures per item (how many come back as too small or too large) help us too.
2. We set it and let you know. The size advice on your product pages changes with it; nothing needs to change in your shop.
Want the size advice one size larger (or smaller) on all your products? Tell us, with one example: a product, the answers you filled in (height, weight and the other questions) and the size you get and expect. We adjust it for your whole shop.
What the True to Size values mean: how far the item is from its size chart.
| True to Size | The item | Shoppers are advised |
| --- | --- | --- |
| `-1` | runs a size small | one size bigger |
| `-0.5` | runs a bit small | half a size bigger |
| `+0.5` | runs a bit large | half a size smaller |
| `+1` | runs a size large | one size smaller |
Your value counts together with the adjustments we make automatically from your return data: both count, so check the advice after you set it. You see the change in the size advice for that product. The Fit Bar on your product page shows it only when the Fit Bar is switched on for your shop: ask us whether it is on for yours.
Is the size advice off for products you don't know to run small or large? Send us a link to one or two of them, the answers filled in (height, weight and the other questions), the size advised and the size that fits, and we check them for you.
