Why the “Find My Size” Feature Works

Most websites offer size charts, but they’re hard to understand — and don’t reflect how clothes really fit. Some charts are based on outdated data. Others assume you fit a generic body type (spoiler: most of us don’t).

With Tellar’s size finder tool, you’ll get smart suggestions based on:

1. Store Size Lookup

• Brand-specific data (we account for how each brand “runs”)
• Fabric behaviour (like shrinkage and stretch)
• Cut and fit of the item (e.g. oversized vs tailored)
• Your preferred units (CM or Inches)

This makes it the most accurate clothing size tool available for everyday shoppers.

 

 

Can’t Measure Yourself? No Problem

Don’t know your exact measurements? You’re not alone. That’s why Tellar lets you build your profile in two ways:

Option 1: Manual Entry

Use a tape measure to input:

• Chest: Around the widest part of your chest or bust
• Waist: The narrowest part, above your belly button
• Hips: The fullest part of your lower body

Option 2: Store-Based Estimation

If you already know your size in a brand like ASOS or Mango, just enter it. We’ll reverse-engineer your measurements and show your equivalent size across 1500+ brands.

You’ll still get personalised size recommendations, no tape measure required.

International Sizing Doesn’t Have to Be Confusing

Online shoppers often get stuck converting between:

• UK to US sizes (a UK 10 ≠ US 10!)
• UK to EU (EU 38 can be UK 10 or 12, depending on brand)
• Men’s and women’s sizing formats

Tellar’s UK clothes sizing tool automatically translates your size across regions — so you can shop confidently on UK, US, and European websites without second-guessing.

Say Goodbye to Size-Based Returns

One of the top reasons for online returns is poor fit. It’s costly for stores and frustrating for you.

With Tellar’s online clothes sizing system, you can:

• See your size in the item before you buy it
• Avoid unnecessary returns and shipping fees
• Build a consistent wardrobe that actually fits your body

In fact, users who build a Tellar.co.uk profile report 40% fewer returns after their second purchase.

Pro Tips for a Better Fit

🎯 Check fabric type: Stretchy materials can handle slight sizing up or down, but rigid denim or woven fabrics? Not so much.

🎯 Update measurements twice a year: Weight shifts, posture, and body shape changes can throw off sizing over time.

🎯 Differentiate between oversized and poor fit: If a garment is meant to be loose, Tellar will account for that. If it just fits badly? You’ll know.

🎯 Coats, jackets, and layers: It’s smart to size up if you’ll be wearing thick layers underneath.
