Add Tailor Size Guide as a preferred source on GoogleThe fastest way to reduce apparel returns on Shopify is to fix wrong-size orders before they happen: put an accurate, product-specific size chart next to the size selector, add a size recommender for shoppers who won't measure, show fit notes and model sizes, and make exchanges easier than refunds. Then measure size-related returns by product, because a few items usually cause most of the problem.
Returns are a big line on any clothing store's P&L. The National Retail Federation estimates that 19.3% of online sales were returned in 2025, compared with 15.8% across retail overall. This guide walks through the tactics that target the most preventable part of that, wrong size and poor fit, in the order I'd tackle them. Tailor Size Guide is our app and comes up where it fits, but every tactic here works with whatever tools you use.
Key takeaways
- Online return rates run above retail overall: 19.3% vs 15.8% of sales in 2025 (NRF).
- Wrong size and fit are the most preventable apparel returns. Start there.
- Order of attack: accurate charts → recommender → fit notes → exchanges → measure by product.
- Don't trust any single 'X% fewer returns' figure, ours included. Measure your own before/after.
- Use the returns cost calculator to see what returns cost your store.
Why apparel returns are so high
Clothing is hard to buy online for a simple reason: you can't try it on. A shopper has to translate a photo, a size label and maybe a chart into a guess about how the garment will fit their body. When that guess is wrong, the item comes back.
The NRF's 2025 returns research puts online returns at 19.3% of sales, higher than the 15.8% rate across all retail, and it also estimates that around 9% of returns are fraudulent. Industry studies of return reasons consistently rank size and fit as the leading reason clothing is returned, though the exact share varies a lot from study to study. So treat it as a range, not a single number.
What matters for you is the split between returns you can prevent and returns you can't:
| Return reason | Preventable before purchase? | What fixes it |
|---|---|---|
| Wrong size | Yes, mostly | Accurate charts, recommender, fit notes |
| Fit or style different from expected | Partly | Better photos, model info, fit descriptions |
| Damaged or defective | Partly | Quality control, packaging |
| Changed mind | Rarely | Clear policy, not much else |
| Ordered several sizes on purpose | Yes, partly | Sizing confidence, see bracketing |
| Fraud and abuse | Separate problem | Policy and detection, see fraudulent returns |
Wrong-size returns are the biggest preventable category, and they're also the cheapest to fix, because the product is fine. The shopper just didn't have enough information at the moment they chose a size.
Tactic 1: Put an accurate, product-specific size chart next to the size selector
This is the foundation. Everything else on this list works better when the size chart is right.
Make it product-specific. A slim tee and a relaxed hoodie shouldn't share a chart. If a store-wide chart says "Medium = chest 38 to 40 inches" but your relaxed hoodie measures 46 inches across the chest, shoppers who read the chart will size down and be disappointed, and shoppers who don't will be swimming in fabric. Charts should reflect the garment's actual measurements, or at least the body measurements that particular cut is designed for.
Say what kind of measurement it is. "Body measurements" (fit your body to these) and "garment measurements" (the item laid flat) are different numbers. Charts that just say "chest" get misread constantly, and that alone causes avoidable returns.
Put it where the decision happens. A size chart link two scrolls below the size buttons, or hidden in a description tab, doesn't get used. Place it right next to the size selector, and check it on a phone. Our guides on where to place a size chart and mobile size charts go into detail.
Use a text table, not an image. Images get blurry on phones and can't be read by screen readers or translated. A real table works everywhere.
Show both inches and centimetres if you ship outside the US, or offer a cm/inch switch.

Tactic 2: Help shoppers who won't measure
Many shoppers will never pick up a tape measure. For them, a size chart is a table of numbers they can't use. Three things help:
- A size recommender. It asks a few questions the shopper can answer from memory, such as height, weight, usual size in a brand they know, and how they like things to fit, and recommends one size for that product. Our size recommender page explains how ours works, and our article on whether fit recommenders reduce returns looks at where they help and where they don't.
- "Usual size" anchors. Even without a recommender, a line like "If you wear a Medium in most high-street brands, take a Medium here" or "runs small, size up" gives shoppers a reference they understand.
- Measuring help that's easy to find. Link short guides from the product page, such as how to measure your chest or how to measure your waist, and keep diagrams in the chart itself.
Tactic 3: Show how the garment actually fits
A size chart tells shoppers what the garment measures. It doesn't tell them how it looks or feels on a body. Fill that gap:
- Model information: the model's height and the size they're wearing ("Model is 5'9" and wears a Small"). It's one of the simplest and most useful lines on a product page. Our guide to size charts with model info shows how to add it.
- Fit description: "Relaxed through the body, cropped at the waist" or "Slim fit; size up if you're between sizes."
- Fabric and stretch: a 100% cotton tee and a cotton-elastane tee in the same size fit differently. Our guide to size charts with fabric info covers this.
- Fit feedback from reviews: aggregate "runs small / true to size / runs large" from customer reviews and show it near the size selector. See showing fit feedback from reviews.
Tactic 4: Be careful with "international" sizes
If you sell abroad, size labels can be a trap. A UK 10 is a US 6; an EU 38 is a US 6 or 8 depending on the brand; Asian sizes often run smaller than Western ones. Shoppers converting in their heads get it wrong.
- Show the sizes your customers know, for the markets you sell to.
- Use body measurements as the common language between systems.
- Consider showing sizes by market, which our guide on localizing size charts by country covers.
The international size converter is useful for checking your own conversions.
Tactic 5: Make exchanges easier than refunds
Some returns will happen no matter what. When a shopper sends something back because it's the wrong size, they usually still want the product. An exchange keeps the sale; a refund loses it.
- Offer the exchange first in your returns flow, with the refund still clearly available.
- Make the exchange cheap or free where you can; the margin math usually favours it.
- Make sure the second size is right. If the shopper guessed wrong once with no better information, they'll guess wrong again.
Shopify supports returns and exchanges in the admin, and self-serve returns through customer accounts, and many returns apps add exchange-first flows on top. Our guides to exchange-first returns and store credit vs refunds go deeper.
Tactic 6: Write a return policy that sets expectations
A clear policy doesn't reduce wrong-size returns directly, but it does reduce friction, disputes and serial returning. State the window, the condition items must be in, who pays shipping, whether exchanges are free, and any items that can't be returned (personalised or made-to-measure items, for example). Our guide to writing a return policy that converts has a template.
Tactic 7: Measure size-related returns by product
This is the tactic most stores skip, and it's the one that tells you where to spend your effort.
- Collect a return reason for every return, with "too small" and "too large" as separate options.
- Report by product, not just store-wide. A single product with a mis-measured chart can produce a big share of your size returns.
- Fix the worst products first: check the chart against the real garment, add a "runs small" note, or adjust the recommender.
- Compare before and after each change, over the same season if you can.
| Metric | Why it matters |
|---|---|
| Return rate for "too small" and "too large", by product | The core signal for sizing problems |
| Exchange rate for a different size | Shows where shoppers liked the product but missed the size |
| Orders with two sizes of the same item | Your bracketing rate |
| Size chart and recommender usage by product | Low usage usually means poor placement |
| Conversion rate on products with sizing tools | Sizing confidence often helps conversion too |
Our guide to analysing return data to improve product pages walks through it step by step, and the returns cost calculator puts a money value on the change.
Mistakes to avoid
- Using one size chart for every product. It's quick, and it's the most common cause of avoidable size returns.
- Copying a chart from another brand. Their pattern isn't your pattern.
- Hiding the chart. If shoppers can't find it next to the size buttons, it doesn't exist.
- Images instead of tables. Unreadable on phones.
- Only measuring store-wide return rates. The fix is almost always product by product.
- Making refunds hard instead of exchanges easy. It annoys customers and doesn't recover the sale.
A checklist you can work through this week
- List your 10 most-returned products and their return reasons.
- Check each one's size chart against the actual garment.
- Add model height and size, and a one-line fit note, to each.
- Move the size chart link next to the size selector, and test on a phone.
- Add a size recommender to products where size returns are highest.
- Make exchanges the first option in your returns flow.
- Set a date to compare size-related returns before and after.

Frequently asked questions
What is the average return rate for online clothing?
There isn't one reliable single number for apparel, but the National Retail Federation estimates 19.3% of all online sales were returned in 2025, compared with 15.8% across retail overall. Clothing typically returns above the online average because it can't be tried on.
What is the main reason clothes are returned?
Studies of return reasons consistently rank size and fit as the leading reason clothing is returned, though the exact share varies between studies. It's also the most preventable reason, because the product itself is fine.
How can I reduce wrong-size returns on Shopify?
Put an accurate, product-specific size chart next to the size selector, add a size recommender for shoppers who won't measure, show model size and fit notes, and track size-related returns by product so you can fix the worst items first.
How much can a size chart reduce returns?
It depends on your products and how poor your sizing information was before. Rather than relying on a headline percentage, compare size-related return rates for the same products before and after you make the change.
Should I offer free returns?
Free returns can lift conversion but increase return rates and costs. Many stores offer free exchanges and paid refunds, which keeps the sale while discouraging returns. Run the numbers for your margins with a returns cost calculator.
Do exchanges reduce the cost of returns?
An exchange still costs shipping and handling, but it keeps the revenue, while a refund loses it. For wrong-size returns, exchange-first flows usually make financial sense.
