Brand Size Comparison: A Smarter Approach to Online Clothing Fit
In the evolving landscape of online fashion retail, one persistent issue remains: inconsistent sizing across brands. The absence of a global sizing standard, coupled with subjective interpretations of fit, leaves consumers uncertain and contributes to high return rates, lost revenue, and customer dissatisfaction.
To address this growing challenge, Tellar.co.uk offers a reliable, data-driven solution — a free, browser-based tool that enables users to compare their clothing size across more than 1,500 brands in real time. This article explores the importance of brand size comparison, the underlying causes of sizing inconsistencies, and how Tellar offers a scalable, intelligent alternative to guesswork.
The Problem: Inconsistent Sizing Across Fashion Brands
Despite technological advances in e-commerce, sizing remains largely unstandardized. A consumer who wears a size 10 in Zara may require a size 12 in Reiss, or a size 8 in H&M, depending on how the brand defines its fit. This inconsistency stems from several factors:
-
Lack of industry-wide measurement standards
-
Region-specific size frameworks (e.g. UK vs. US vs. EU)
-
Design variation (e.g. slim fit vs. relaxed fit)
-
Brand positioning and demographic targeting
These discrepancies undermine consumer trust and introduce friction into the online shopping experience. Studies suggest that over 40% of fashion returns are due to sizing issues — a statistic that has both financial and environmental implications.
The Role of Brand Size Comparison Tools
Brand size comparison is a modern approach that allows users to translate their known size in one brand into an estimated equivalent in another. Instead of relying solely on generic size charts, which can be misleading or overly simplified, comparison tools use:
-
Actual garment measurements
-
Brand-specific fit data
-
Adjustment algorithms that account for how each label typically sizes their garments
This functionality empowers users to shop across multiple retailers with confidence, minimizing the risk of ordering incorrect sizes.
Introducing Tellar: The UK’s Premier Brand Size Comparison Platform
Tellar.co.uk is a free, web-based size recommendation tool developed to support online shoppers across the UK and beyond. Unlike brand-locked or app-based solutions, Tellar operates independently, allowing users to compare sizes between any of the 1,500+ supported brands.
Key Features:
-
Dual Input Method: Users can enter either their body measurements (chest, waist, hips) or a brand and size they already wear.
-
Cross-Brand Comparison: Tellar returns the most accurate size recommendation in the target brand based on real-world data and measurement alignment.
-
Unit Flexibility: The tool supports both metric (cm) and imperial (inches) inputs.
-
Fit Intelligence: Adjusts recommendations based on brand tendencies (e.g. “runs large”, “slim fit”).
-
Instant Output: Size suggestions are displayed in seconds without the need to register or download an app.
Example Use Case: Cross-Brand Fit Translation
A customer who typically wears a Size 10 in ASOS may wish to purchase trousers from Reiss. Instead of ordering multiple sizes or consulting inconsistent size guides, the user visits Tellar.co.uk:
-
Selects “I know my size in a store”
-
Inputs ASOS and Size 10
-
Chooses Reiss as the target brand
The system analyses size equivalency and fit characteristics across both brands and recommends Size 12 in Reiss — a more accurate result based on known variations in their sizing patterns.
