Myntra Size Chart Standards Explained (2025 Seller Guide)

If you've ever had a Myntra listing rejected because of "incorrect size chart" or watched your return rate climb because customers ordered the wrong size, you already know: Myntra's size chart standards aren't suggestions—they're non-negotiable requirements.

For Indian marketplace sellers, especially those managing 500+ SKUs across Myntra, Flipkart, and Amazon, understanding these standards can mean the difference between 15% and 35% return rates. And in fashion, where returns already eat 25-30% of margins, every percentage point matters.

This guide breaks down exactly how Myntra's size chart system works, what triggers rejections, and how to standardize your size data across categories without spending 6 hours per product.

Why Myntra's Size Chart Standards Are Stricter Than Other Marketplaces

Myntra processes over 5 lakh fashion orders daily. Unlike Amazon (which sells everything) or Flipkart (which started with electronics), Myntra built its entire quality system around fit accuracy.

Here's what makes their standards unique:

• Category-specific mandatory fields: Tops need different measurements than bottoms. Myntra enforces 8-12 mandatory measurement points depending on category.
• Measurement tolerance limits: Your S-size shirt can't have a 40-inch chest. Each size has acceptable ranges.
• Regional sizing requirements: Indian Standard Sizes (ISS) are mandatory for ethnic wear; international sizes (S/M/L or numerical) follow different rules.
• Material-based variations: Stretchable fabrics have different size chart requirements than non-stretch materials.

A seller we worked with had 342 listings rejected in one upload batch—all because they copy-pasted Amazon size charts without adjusting for Myntra's ethnic wear measurement standards. That's 30+ hours of rework.

Myntra Size Chart Categories: What You Must Know

Myntra divides size charts into clear categories. Here's the breakdown sellers actually need:

1. Men's Apparel Size Standards

Tops (Shirts, T-shirts, Kurtas):

• Mandatory measurements: Chest, length, shoulder width, sleeve length
• Optional but recommended: Neck size (for formal shirts), armhole depth
• Size progression: Must maintain 2-inch chest difference between consecutive sizes
• Common rejection: Listing "Chest: 38-40" for Medium—Myntra wants exact measurements (e.g., "Chest: 39 inches")

Bottoms (Jeans, Trousers, Shorts):

• Mandatory: Waist, hip, length, inseam
• Size format: Accept both waist-inch (30, 32, 34) and alpha sizes (S/M/L)
• Front rise and leg opening increasingly required for premium denim

2. Women's Apparel Size Standards

Western Wear (Tops, Dresses, Jeans):

• Mandatory: Bust, waist, hip, length
• Size range: XS to 6XL (Myntra enforces inclusive sizing)
• Bust-waist-hip progression must be anatomically logical (no 34-28-36 jumping to 36-26-38)

Ethnic Wear (Kurtas, Sarees, Salwar Suits):

• Different measurement system entirely
• Kurtas: Bust/chest, waist, hip, length, sleeve length, armhole
• Saree blouses: Bust, waist, shoulder, sleeve length, blouse length
• Size format: Often Free Size, or XS-7XL with ethnic draping considerations

One ethnic wear seller told us: "Myntra rejected 80% of my kurta listings because I didn't include 'kalidar' flare measurements for anarkalis. Amazon never asked for this—but Myntra's customers expect it."

3. Kids' Apparel Size Standards

This is where sellers make the most mistakes:

• Age-based sizing mandatory (0-3M, 3-6M, 6-12M, 1-2Y, etc.)
• Height-based sizes for 2Y+ (height in cm is mandatory field)
• Cannot use adult size terminology (no "Small" for kids—must be age/height specific)
• Safety compliance fields (fabric certifications) often required

Common Myntra Size Chart Rejection Reasons (And Fixes)

After analyzing 2,000+ rejected listings from sellers we've helped, here are the top culprits:

How to Create Myntra-Compliant Size Charts (Step-by-Step)

Step 1: Identify Your Exact Category

Don't guess. Log into Myntra Seller Portal → Product Listing → Check the category tree. A "kurta" under Women's Ethnic has different requirements than a "tunic" under Women's Western.

Step 2: Download Myntra's Official Size Chart Template

Myntra provides Excel templates for each category. These aren't optional guides—they're the exact format your data must match.

• Location: Seller Portal → Resources → Size Chart Templates
• Critical: Use the template dated within last 6 months (Myntra updates these quarterly)

Step 3: Measure Actual Garments

This is non-negotiable. Don't estimate; don't copy competitor listings. Actual measuring tape on actual product.

Pro measurement tips:

• Lay garment flat on hard surface
• Chest/bust: Measure armpit to armpit, multiply by 2
• Length: Highest shoulder point to bottom hem
• Shoulder: Seam to seam across back
• Sleeve: Shoulder seam to cuff edge

Step 4: Fill Template with Precision

• Use whole numbers or .5 decimals only (no "38.75 inches")
• Every size must have every mandatory measurement
• If offering Free Size, you still need to provide measurement range

Step 5: Create Size Chart Image

Myntra requires both structured data AND a visual size chart image:

• Dimensions: Minimum 800x800px, maximum 2000x2000px
• Format: JPG or PNG
• Must include: Brand logo, all measurements in table format, measurement guide illustration
• Pro tip: Include "How to Measure" diagrams—reduces return queries by 15-20%

Step 6: Upload and Cross-Verify

After upload, check the preview in Seller Portal. Does the size dropdown show correct sizes? Do measurements display properly? 40% of rejections happen because sellers don't verify the preview.

Regional Sizing: Indian vs. International Standards

This confuses many sellers, especially those also listing on Amazon Global or Flipkart:

When to Use Indian Standard Sizes (ISS):

• All ethnic wear (kurtas, sarees, sherwanis, lehengas)
• Traditional footwear (juttis, mojris)
• Required for "Made in India" fashion campaigns

When to Use International Sizes:

• Western wear from international brands
• Sportswear and athleisure
• Imported fashion

The Hybrid Approach: Many successful sellers use both. In the title/description, they mention "Size M (Chest: 38-40 inches, Indian Size: 38)". This catches searches from both customer segments.

Size Chart Automation: How Sellers Handle 500+ SKUs

Let's be real—if you're selling across Myntra, Flipkart, Amazon, and AJIO, manually creating size charts for every product isn't scalable.

Smart sellers use three automation approaches:

1. Template-Based Scaling

Create master size chart templates for each product type you sell:

• One template for men's casual shirts
• One for women's kurtas
• One for kids' t-shirts

For each new product, you only adjust the specific measurements—not rebuild from scratch. Cuts creation time from 15 minutes to 3 minutes per SKU.

2. Bulk Upload with Size Variants

If you're uploading 50 similar kurtas in different colors/prints:

• Create one perfect size chart
• Use it for all variants (assuming fit is identical)
• Myntra's bulk upload allows size chart ID reuse

3. AI-Powered Catalog Automation

For sellers managing 500+ active listings, platforms like EcomCatalog AI can auto-generate marketplace-compliant size charts:

• Upload your product images and basic measurements
• AI maps them to Myntra's required format automatically
• Generates both structured data and visual size chart images
• Adapts same product for Myntra, Flipkart, Amazon size chart standards

One beauty and fashion seller using automated catalogs told us: "We went from 6 hours per product listing across 4 marketplaces to 30 minutes ka kaam. And Myntra rejection rate dropped from 25% to under 3%."

Advanced Tips: Reducing Returns Through Better Size Charts

Beyond just getting approved, smart size charts reduce returns—here's how top sellers do it:

1. Add Fit Notes

Myntra allows a "Fit" field in listings. Use it:

• "Regular fit with slight stretch"
• "Runs small, consider sizing up"
• "Relaxed fit, oversized style"

2. Include Model Measurements

In product images with models, add: "Model height: 5'8", wearing size M." Customers can better visualize fit.

3. Provide Fabric Stretch Information

"100% cotton, no stretch" vs. "95% cotton, 5% elastane, slight stretch" helps customers make informed decisions.

4. Regional Language Support

For ethnic wear, some sellers add Hindi measurement terms in brackets: "Length (lambai): 42 inches." Small touch, builds trust with vernacular shoppers.

Size Chart Compliance Checklist (Before Every Upload)

Print this, keep it next to your workspace:

• ☐ Category template downloaded (within last 6 months)
• ☐ All mandatory measurements filled for all sizes
• ☐ Measurements are actual garment measurements (not estimated)
• ☐ Size progression is logical (2-2.5" increments)
• ☐ Units specified clearly (inches/cm)
• ☐ Size chart image created (800x800px minimum)
• ☐ Image measurements match catalog data exactly
• ☐ Preview checked in Seller Portal before final submit
• ☐ Fit notes added (if applicable)
• ☐ Return policy clearly stated

What to Do When Myntra Still Rejects Your Size Chart

Even with perfect data, rejections happen. Here's your action plan:

Step 1: Read the Exact Rejection Reason

Myntra's rejection emails are specific. Don't ignore them. They tell you exactly which field is wrong.

Step 2: Compare Against Approved Similar Products

Search Myntra for similar products from successful sellers. Check their size charts (visible on product pages). What format are they using?

Step 3: Contact Myntra Seller Support

Use the Seller Portal ticket system. Attach:

• Your product Excel sheet
• Size chart image
• Screenshot of rejection
• Reference to similar approved products

Response time: Usually 24-48 hours.

Step 4: Learn from Patterns

If 20 kurtas got approved but 5 anarkalis got rejected, the issue is category-specific. Myntra's anarkali requirements likely differ from straight-cut kurta requirements.

Final Thought: Size Charts as Competitive Advantage

Most sellers see size chart compliance as a checkbox—something to get through so listings go live. But the best sellers we've worked with treat size charts as a conversion optimization tool.

When your size charts are more detailed, clearer, and more helpful than competitors', you don't just reduce returns—you increase buy confidence. That 2% conversion rate becomes 2.8%. On 10,000 monthly visitors, that's 80 extra sales.

And in Indian fashion e-commerce, where trust decides purchase, that detailed size chart—with actual measurements, fit notes, and fabric details—becomes your silent salesperson.

If you're scaling across multiple marketplaces and need size charts auto-generated in marketplace-compliant formats, EcomCatalog AI's Myntra catalog automation can handle the heavy lifting—so you can focus on what actually grows your business.
