Returns are the biggest headache for online fashion sellers. In India, clothing return rates can run at 20–35% for brands without proper size guidance — and each return costs you time, money, and potential customer goodwill. The good news is that a well-designed size guide on your Shopify store can cut your return rate significantly. This guide explains how to create one that actually works.
Why Size Guides Reduce Returns
Most clothing returns happen because the garment did not fit as expected. This is almost always a problem of insufficient information — the customer did not have enough data to make a confident size choice. A good size guide solves this by giving customers the measurements they need to self-select the right size before ordering. Less guesswork equals fewer returns.
What a Size Guide Should Include
A size guide for Indian clothing should go beyond just showing a table of S/M/L/XL. It needs:
- Actual body measurements — chest, waist, hips, and inseam (for bottoms) in both inches and centimetres
- How to measure yourself — a short illustrated guide showing where to place the tape measure
- Garment measurements — the actual dimensions of the garment, not just the body measurements it fits
- Fit guide — is this garment slim fit, regular fit, or relaxed? Does it run large or small?
- Fabric stretch information — does the fabric have any give? This affects which size to choose
- A recommendation for in-between sizes — “If between sizes, we recommend sizing up for a relaxed fit”
Tools to Add a Size Guide on Shopify
There are several good options for adding size guides to your Shopify store:
Kiwi Sizing is the most popular dedicated size guide app on Shopify. It lets you build product-specific size charts, add a “Find My Size” recommendation tool, and display guides as a popup on product pages. Its fit quiz feature — where customers answer a few questions about their body and preferences — is particularly effective at reducing size uncertainty.
Size Chart & Size Guide by Experts is another solid option with clean popup formatting and the ability to add different charts for different product types (tops vs bottoms vs dresses).
For advanced AI-based size recommendations, Fit Quiz by Sizebay collects body measurements and garment preferences to give personalised size recommendations — particularly useful for brands with complex sizing like ethnic wear or activewear.
Creating Separate Size Guides for Different Product Types
One size guide does not fit all. A kurti size chart is completely different from a trouser size chart or a lehenga size chart. Create separate guides for:
- Tops, shirts, and kurtas (chest, shoulder, length)
- Bottoms and trousers (waist, hips, inseam, rise)
- Dresses and salwar suits (bust, waist, hips, length)
- Lehengas (skirt waist, length, choli bust)
- Kids clothing (height and weight alongside age and measurements)
Where to Place the Size Guide on Product Pages
Placement matters enormously. The size guide link should be visible without scrolling, right next to the size selector. A “Size Guide” link that customers have to hunt for is nearly useless. Best practice:
- A clickable “Size Guide” text link directly below the size selector
- Opens in a popup so customers stay on the product page
- On mobile, ensure the popup is scrollable and easy to read on small screens
Adding a “How to Measure” Section
Many customers, particularly in tier-2 and tier-3 cities where online fashion is newer, do not know how to measure themselves accurately. Add a simple illustrated guide or a short video showing exactly where to place the measuring tape. This small addition dramatically increases confidence in the sizing information customers are reading.
Testing and Improving Your Size Guide
After adding a size guide, monitor your return rate by reason. Most courier partners and Shopify return apps let you collect return reasons — track “wrong size” returns specifically. If they are still high for certain products, update the size guide with more specific information or customer-reported feedback like “This style runs small — most customers size up.”

Frequently Asked Questions
How much can a size guide actually reduce returns?
Well-implemented size guides typically reduce size-related returns by 20–40%. The impact varies by product type — complex garments like ethnic wear and activewear benefit more than simple basics. Combined with accurate model photography showing the garment on different body types, the reduction can be even greater.
Should I use Indian sizes (S/M/L) or UK/US sizes on my Shopify store?
Use Indian size labels with actual measurements alongside them. Avoid relying solely on S/M/L without measurements — Indian sizing varies enormously between brands and customers know this. Showing the actual chest, waist, and hip measurements removes all ambiguity. If you sell internationally, add UK and US size equivalents to your chart.
What is the best free option for a Shopify size guide?
The simplest free option is to create a dedicated size guide page on Shopify and link to it from your product descriptions. Use a table in the Shopify page editor to format your size chart. For a more polished popup-style guide without paying for an app, you can use Shopify’s free theme popup features or embed a popup via a small snippet of code in your product template.
