# How accurate is nista's virtual try-on fit?

nista describes its fit accuracy as "very close." Your avatar is built from a few photos of you and keeps your real proportions, and nista says much of its research goes into rendering each piece of clothing accurately. That makes nista useful for judging how an item will sit on your body, but it isn't an exact sizing guarantee, so check the store's size chart before you order.

## Key takeaways

- nista calls its fit "very close," not exact.
- Your avatar keeps your real proportions because it's made from photos of you.
- nista focuses much of its research on rendering each garment accurately.
- Use nista together with the store's size chart and your own measurements.
- nista doesn't publish an accuracy percentage, so be wary of anyone quoting one.

## What "very close" means in practice

nista's own words are: "very close. your avatar keeps your real proportions, and much of our research goes into rendering each piece of clothing accurately." Two things drive that:

1. **Your proportions.** The avatar is made from a few photos of you rather than a generic body type, so the relationship between your shoulders, waist, hips, and leg length carries over.
2. **The garment.** nista puts much of its research into how each piece of clothing renders, so the cut and shape of the item you're looking at are represented on your avatar.

Together, those let you see things a model photo can't show you: whether a coat hits your hip or mid-thigh, whether wide-leg trousers swamp your frame, or whether a cropped top lands where you'd like it to.

## What a virtual try-on can and can't tell you

Treat nista as a visual fit check, not a tape measure.

| Good for judging | Still check elsewhere |
|---|---|
| Overall silhouette on your body | The exact size to order |
| Length of hems, sleeves, and inseams relative to you | Fabric stretch and feel |
| How proportions of a cut work with yours | Brand-specific sizing quirks |
| Comparing several styles quickly | The store's return policy |

Fabric behavior is the clearest example. Two pairs of jeans can look similar on screen, but one has stretch and one doesn't, and that changes how a given size feels. The product description and size chart are the place to check that. For more, see [how to find jeans that fit](/guides/how-to-find-jeans-that-fit).

## How to get the most accurate result

A few habits make the try-on more useful:

1. **Make your avatar carefully.** Take the photos for your avatar with care so it reflects your real proportions.
2. **Read the size chart first.** Pick your likely size from the store's chart, then use nista to see the cut and length on you.
3. **Compare against clothes you own.** Measure a similar item that fits you well and compare it with the chart's numbers.
4. **Check the product details.** Look for fabric content, stretch, and whether the brand says it runs small or large.
5. **Try a few styles.** Seeing two or three options side by side on your avatar is often more revealing than looking at one.

## Why sizing still differs between brands

Even with a perfect picture of how something looks, a "medium" at one brand isn't a "medium" at another. Brands cut for different body shapes and use their own measurement standards, and the same brand can size differently across product lines. That's why nista's honest framing matters: it shows you the garment on your proportions, while the store's size chart tells you which label maps to your measurements. You need both.

## Is it accurate enough to be worth using?

If your goal is to stop guessing what something will look like on you, nista is built for that, and it's free; [here's how nista makes money](/nista/is-nista-free). Brands partner with nista because try-ons lead to fewer returns. Just keep your expectations right: very close, not perfect.
