At Tellar.co.uk, we take the guesswork out of shopping for trousers. By comparing your body measurements across 1,500+ brands, we show you exactly which size to buy — in seconds.

This guide explores the best high street and designer brands for trousers, what to expect from their sizing, the fits they’re known for, and how to shop smarter.

Why Trousers Are So Hard to Shop For

Unlike jeans, where waist sizes are often labelled numerically, trousers come in every naming format imaginable — S, M, L; UK 10, EU 38; tailored fit, regular fit, slim leg, wide leg — and not every brand defines these the same way.

➡️ A UK 12 in one store could be a UK 10 or 14 in another

➡️ Your hips may place you in a different size than your waist

➡️ Different cuts (like tapered or wide-leg) can dramatically alter the fit

That’s where Tellar.co.uk steps in. Instead of navigating guesswork, create a free profile, enter your measurements once, and we’ll match you with the right size in every brand — automatically.

Materials Matter: What Your Trousers Are Made From

The fabric composition makes a major difference in comfort and longevity:

• Polyester blends: Affordable, easy to care for, but less breathable

• Cotton: Comfortable, versatile, prone to wrinkling

• Wool: Ideal for winter trousers and workwear, more structured

• Linen: Great for summer, but creases easily

• Elastane/stretch blends: Allows movement, perfect for fitted trousers

Tip: Always check fabric labels when trying new brands. Tellar stores this info for each item where available.

What to Avoid When Buying Trousers

• Blindly ordering your ‘usual’ size — it won’t be consistent across brands

• Ignoring fabric stretch — even a 5% elastane blend can change fit

• Skimming over the size chart — or worse, not being given one

• Assuming your waist is your trouser size — hips often determine fit

• Buying without checking return policies — especially for overseas brands

Would you like a second version of this tailored to men’s trousers or smart vs casual styles?

Absolutely — here is a more factual, technical, and polished 1300-word pillar post on:

Choosing the right trousers is more complex than it seems. Between inconsistent sizing, variable fabric compositions, and wildly different brand fit philosophies, consumers often struggle to find trousers that truly fit — especially across multiple brands.

At Tellar.co.uk, we simplify this. Our platform compares your exact body measurements to sizing data from 1,500+ brands, offering real-time size recommendations tailored to your proportions. No more guesswork. No more returns.

This technical guide outlines the best brands for trousers by category, fabric and fit characteristics, sizing consistency, and key user considerations.

1. Why Trousers Are the Most Complex Garment to Size

Trousers present a unique sizing challenge for both manufacturers and consumers due to:

• Multi-point measurement dependency: Waist, hips, rise, thigh, inseam, and leg opening all contribute to fit

• Different rise and cut types (mid-rise vs. high-rise, straight vs. tapered) change how the trousers fit your body

• Inconsistent size grading across brands, especially between high street and designer labels

• Lack of standardised international size charts: A UK 12 is not universally equivalent to a US 8 or EU 40

Tellar.co.uk maps out this complexity using proprietary measurement algorithms. You enter your chest, waist, and hips, and we identify the correct size in brands with known discrepancies.

2. Trousers by Category: What Makes a Brand Stand Out?

Different brands optimise for different demographics, tailoring their trousers for specific silhouettes, fabrics, and sizing schemes. Below is a brand-by-brand breakdown by technical fit category:

For Curvy and Hourglass Body Types

• Good American: Engineered with a contoured waistband and stretch blends, these trousers minimise waist gaping and accommodate hip-to-waist ratios above 0.75.

• Boden: Offers curve-friendly sizing and mid-weight cotton blends with elastane. Petite and tall ranges available.

• White Stuff: Uses more generous hip proportions and natural fibres. Ideal for soft tailoring and everyday casual wear.

📌 Find your size in Good American or Boden with Tellar

---

For Straight or Athletic Builds

• COS: Known for architectural tailoring and straight cuts, COS trousers often have a high waist-to-hip ratio (close to 1:1). Minimal stretch.

• Arket: Follows Nordic size grading — generally more linear through the waist and thigh.

• Reiss: Excellent for slim or rectangular builds. Slim-cut trousers with sharply tailored finishes.

📌 Use Tellar to compare COS, Arket, and Reiss sizes

---

For Petite Frames (Under 5’3”)

• ME+EM: Offers shorter inseams, tailored rise adjustments, and high-waisted options that elongate the leg line.

• Mango Petite: Slightly narrower waists and shorter leg lengths in their petite line. Often run small — Tellar adjusts for this.

• Jigsaw Petite: Classic British tailoring with petite-friendly proportions.

📌 Check ME+EM or Mango Petite sizing instantly

---

For Tall Builds (Over 5’9”)

• Long Tall Sally: Specialises in inseams up to 38 inches. Leg proportions and rise are designed for tall women, not just longer trousers.

• COS: Offers longer rise and inseam options naturally due to their minimalist cuts.

• Everlane (US sizing): Certain trousers run long and lean. Tellar auto-converts these from US to UK/EU standards.

📌 Use Tellar to check inseam compatibility across brands

3. Fabric Analysis: The Science Behind Comfort and Structure

When it comes to trousers, fabric composition directly impacts:

• Stretch and fit adaptability

7. Pro Tips for Buying Trousers Online

• Use your largest measurement (usually hips) when in doubt — trousers fit tighter there

• Avoid ignoring inseam — especially for petite or tall shoppers

• Always check the stretch content — 1-3% elastane changes everything

• Look for rear darts, pleats, or contoured waistbands — they indicate a better fit

• Save time by using Tellar instead of scrolling through brand size charts

📌 Tellar’s size database includes material and cut notes
