Size Guide Prompt Templates

AI prompt templates for size guides. Help customers choose the right size and reduce returns.

Overview

Size guides directly reduce returns and increase confidence. Most customers won't buy clothes or shoes online if they're unsure about fit. A clear size guide with real measurements and fit tips turns hesitation into purchases.

Best Practices

1

Include actual measurements, not just S/M/L. People know their body measurements; they don't know what 'Medium' means at your store.

2

Explain your fit philosophy. Does this brand run small? Is this style meant to be oversized? Say it clearly.

3

Add a 'between sizes' recommendation. Most people fall between sizes and need guidance on whether to size up or down.

4

Use comparison brands when helpful. 'Fits similar to Levi's 501' is more useful than abstract measurements for some shoppers.

Prompt Templates

1. Apparel Size Guide

Write a size guide for [PRODUCT TYPE] at [BRAND NAME]. Size range: [SIZES]. Include measurement instructions and a size chart. Fit style: [FIT]. Add advice for customers between sizes.
Product: Women's t-shirts. Brand: Evergreen Basics. Sizes: XS-XXL. Fit: Relaxed fit, meant to be slightly loose.
Women's T-Shirt Size Guide

Our t-shirts have a relaxed fit with a little extra room through the body. They're not tight, but they're not boxy either.

How to measure:
Chest: Measure around the fullest part of your chest, keeping the tape level.
Length: Measure from your shoulder (where a seam would sit) to where you want the shirt to end.

| Size | Chest | Length |
|------|-------|--------|
| XS | 34" | 25" |
| S | 36" | 25.5" |
| M | 38" | 26" |
| L | 40" | 26.5" |
| XL | 43" | 27" |
| XXL | 46" | 27.5" |

Between sizes? Size up for a more relaxed feel, or down if you prefer a closer fit. When in doubt, go up. These shirts do shrink slightly after the first wash.

For clothing product pages where fit varies and customers need measurement guidance.

  • •Mention shrinkage if it's relevant. Customers want to know before, not after.
  • •A simple 'how to measure' section prevents measurement errors.

2. Footwear Size Guide

Write a size guide for [SHOE TYPE] at [BRAND NAME]. Include length measurements, width options if available, and fit advice. Mention how this style runs compared to standard sizing.
Shoe type: Running shoes. Brand: Stride Athletics. Width options: Standard and Wide. Fit note: These run about half a size small.
Running Shoe Size Guide

Heads up: These shoes run about half a size small. If you're usually a 10, try a 10.5.

How to find your size:
1. Stand on a piece of paper with your heel against a wall
2. Mark where your longest toe ends
3. Measure from the wall to the mark in inches or centimeters
4. Use the chart below

| US Size | Foot Length (in) | Foot Length (cm) |
|---------|------------------|------------------|
| 7 | 9.5" | 24.1 cm |
| 8 | 9.75" | 24.8 cm |
| 9 | 10" | 25.4 cm |
| 10 | 10.25" | 26 cm |
| 11 | 10.5" | 26.7 cm |
| 12 | 10.75" | 27.3 cm |

Width: Standard width fits most feet. Choose Wide if your feet feel cramped in most running shoes or you have bunions.

For running shoes, you want about a thumb's width of space between your longest toe and the front of the shoe. Your feet swell during runs.

For footwear where sizing varies by brand and style.

  • •If shoes run big or small, say it immediately at the top.
  • •Explain why running shoes need extra room. Education builds trust.

3. Fit Comparison Guide

Write a fit guide comparing different fits of [PRODUCT TYPE] at [BRAND NAME]. Fits available: [FIT OPTIONS]. Help customers choose based on their preferences and body type.
Product: Men's jeans. Brand: Denim Co. Fits: Slim, Straight, Relaxed.
Finding Your Fit

We make the same jeans in three different fits. Same quality, different silhouettes.

Slim Fit
Narrow through the thigh and leg. Not skinny, but close to the body. Works best if you're on the leaner side or want a modern look. If your thighs are muscular, these might feel tight.

Straight Fit
Our most versatile fit. Room in the thigh, straight through the leg. Works for most body types. This is what you want if you're not sure.

Relaxed Fit
Generous through the thigh and seat, slightly tapered leg. More room to move. Good for larger builds, or anyone who prioritizes comfort over a fitted look.

Still not sure? Our best seller is Straight. It works for 80% of customers.

When you offer multiple fits of the same product and customers need help choosing.

  • •Be honest about who each fit works for. 'If your thighs are muscular, these might feel tight' is helpful.
  • •Name your most popular option. Undecided customers will default to it.

4. Ring Size Guide

Write a ring size guide for [BRAND NAME]. Include multiple measurement methods since not everyone has a ring sizer. Add tips for getting an accurate measurement.
Brand: Fine & Simple Jewelry. Products: Wedding bands, statement rings, everyday rings.
Ring Size Guide

Getting your ring size right matters, especially for pieces you'll wear daily. Here are three ways to figure out your size.

Method 1: Measure a ring you already own
Find a ring that fits the finger you're sizing. Measure the inside diameter in millimeters. Match it to the chart below.

Method 2: Use string or paper
Wrap a strip of paper or string around your finger. Mark where it overlaps. Measure the length in millimeters. That's your circumference. Match it to the chart.

Method 3: Order a free ring sizer
We'll mail you a plastic ring sizer. It takes 3-5 days but it's the most accurate method. [Request a Sizer]

| US Size | Diameter (mm) | Circumference (mm) |
|---------|---------------|--------------------|
| 5 | 15.7 | 49.3 |
| 6 | 16.5 | 51.8 |
| 7 | 17.3 | 54.4 |
| 8 | 18.1 | 57 |
| 9 | 19 | 59.5 |
| 10 | 19.8 | 62.1 |

Tips for accuracy:
- Measure at the end of the day when fingers are slightly larger
- Measure the actual finger, not your other hand (they're often different)
- If you're between sizes, go up. You can always resize down.

For jewelry stores selling rings where sizing accuracy prevents returns.

  • •Offer multiple measurement methods. Not everyone has a ring sizer at home.
  • •Mention that finger size changes throughout the day. Prevents returns from tight-fitting rings.

Common Mistakes to Avoid

•

Only showing S/M/L/XL without actual measurements. These labels mean different things at every brand.

•

Hiding fit issues. If a product runs small, say it upfront. Customers appreciate honesty more than discovering it after delivery.

•

Making size guides hard to find. Link to them from every product page, not buried in a footer.
