  • Adds the right variant to cart on completion.
  • Free returns reassurance for the remaining doubters.

What you're trying to do

Apparel and footwear stores have 20-40% return rates, half driven by sizing. A fit quiz that recommends the right size up front captures the shopper's commitment AND reduces the return rate — double win. The math is undeniable: even a 5% return reduction is huge margin recovery.

Things to watch out for

  • Question count — Fudge calibrates to 4 max; more reduces completion.
  • Size chart accuracy — Fudge can audit your size chart against return reasons.
  • Brand sizing — Fudge handles your unique sizing if it differs from industry norm.
  • Variant routing — Fudge handles this: the recommended size auto-applies on add-to-cart.

How Fudge does it

Fudge duplicates your live theme into a draft, builds the quiz template with conditional branching logic, and wires it to your product catalog for result recommendations. Everything starts in draft — preview the quiz end-to-end through each answer path, tweak any question, and publish only when you're ready. Your live store stays untouched.

Why fit quizzes reduce returns and lift conversion at the same time

Apparel returns are dominated by sizing — typically 50%+ of returns are “didn’t fit.” A fit quiz that asks 4 questions about height, usual size, body type, and preferred fit recommends the right size up front, lifting both conversion (shoppers commit faster) and margin (fewer returns).

When this is worth building

Build the fit quiz for apparel, footwear, intimates, or any category where sizing varies meaningfully. Skip for one-size or universally-sized categories.

The quiz works best on the PDP (sized recommendation at the moment of decision) and on a dedicated /pages/fit-finder URL (organic traffic discovery).

What makes a great quiz

  • 4 questions max — more reduces completion rate. Fudge tested and verified.
  • Cross-references your size chart — actual brand-specific sizing, not generic guidance.
  • Recommends the right variant — adds it to cart on completion.
  • Free returns reassurance — for the remaining doubters. Reduces decision anxiety.
  • Mobile-optimized — most fit quiz traffic is mobile.

Common mistakes to avoid

The biggest mistake is the long quiz. 8-question quizzes have 60% completion rates; 4-question quizzes have 85%+. Brevity wins.

The second mistake is generic sizing logic. A 6 in your brand might be a 4 in another. Cross-reference your specific size chart, not generic.

Pair this with return rate analysis and gift recommendation quiz — three tools for systematic conversion + return reduction.

Common questions

What if the customer is between sizes?
Fudge can recommend both with a 'try at home, return free' framing.
Does this work for non-apparel categories?
Yes — supplements (dose recommendations), beauty (concentration recommendations), pet products (breed sizing).
Can it integrate with True Fit / Fit Predictor?
Yes — Fudge can extend those apps or replace them.
