"Find My Size" for Nigerian Fashion Brands: How a Body Scan Picks a Size

For Nigerian fashion brands, a "Find my size" body scan picks a size by measuring the shopper from one photo and their height, then matching those measurements to your own size chart. The shopper sees a single size label, such as "M" or "14", right on your product page.

For your team, this replaces the long WhatsApp back-and-forth of "what's your bust, what's your waist?" with a 30-second step the customer does alone. This guide explains what happens at each stage, what you control as the brand owner, and what it costs. For the wider set of tools, start with our guide to try-on for African fashion brands.

What does the shopper actually do?

The shopper's side takes about half a minute:

1. On your product page, they tap Try it on, then Find my size.
2. They upload one full-length photo of themselves.
3. They type their height.
4. They see a recommended size from your chart.

There is no account to create and no app to download. A customer in Enugu on a mid-range Android phone uses the same flow as a diaspora buyer in Manchester.

How does a single photo become measurements?

The scan uses two inputs: the photo and the height.

• The photo shows the shape and proportions of the body. Pose detection finds key points such as shoulders, waist and hips.
• The height sets the scale. Without it, the scan could tell the shape but not the actual size in centimeters.

Together, they give estimated body measurements. For sizing, pose detection runs in the shopper's browser, so only the measurements are sent to match against your chart. This is worth saying on your page if customers ask about their photos.

How does the scan choose between sizes?

This is where your size chart matters. The scan compares the shopper's measurements to the ranges you entered for that garment type.

It uses the right chart for the garment

You can add one chart per garment type: tops, outerwear, dresses and bottoms. A tops chart may only need chest. A dresses chart can use bust, waist and hips. The scan checks only the measurements that matter for that product.

It sizes up to the largest relevant measurement

Many shoppers don't fall neatly into one size. A customer might be a 12 at the waist and a 14 at the hips. In that case, the scan recommends the size that fits her largest relevant measurement, so the garment closes and sits well.

Here is how that plays out for one dress:

Measurement	Shopper	Your size 12 range	Your size 14 range	Fits
Bust	92 cm	89 to 93 cm	94 to 98 cm	12
Waist	76 cm	73 to 77 cm	78 to 82 cm	12
Hip	106 cm	99 to 103 cm	104 to 108 cm	14
Result				14

Example chart for illustration. Check your brand's own chart.

A size 12 would close at the waist but pull at the hip. The 14 can be taken in at the waist by any local tailor. That is a better outcome than a dress that won't go over the hips.

It falls back to a generic chart if you haven't added one

If you haven't entered a chart for a garment type yet, the scan uses a generic UK, US, EU or AU chart instead. It still gives a size, but adding your own chart makes the label match what you actually cut.

Why does this matter for Nigerian brands specifically?

Three local habits make a scan useful:

• Selling through DMs. Many brands spend hours each day asking for measurements on Instagram and WhatsApp. A scan link on your product page lets customers answer that question themselves.
• Fitted occasion wear. Owambe, wedding and Aso-ebi styles are often close-fitting. A wrong guess shows straight away.
• Diaspora buyers. Overseas customers think in UK and US labels. A scan skips the label and measures them. Our article on diaspora shoppers and UK and US sizes covers how to present your sizes to them.

What do you need to set up as the brand?

You control the result through your size chart. Prepare it before you switch the feature on.

Step 1: Write your chart as body measurements

Use the measurements of the person who fits each size, not the flat width of the garment. Close any gaps between sizes so every shopper falls into a range.

Step 2: Enter it in ZeDaq.ai

Open Dashboard → Size charts, or the size chart section in the Shopify app. Add one chart per garment type and use your own labels. The step-by-step version is in our guide to adding your own size chart.

Step 3: Add the feature to your store

• Shopify: install the ZeDaq.ai Shopify app and switch on its app embed in the theme editor.
• WooCommerce, Wix, Squarespace, BigCommerce or a custom site: paste the ZeDaq.ai script tag into your product template. Lock your API key to your store's domain in Dashboard → API keys. This adds both "Try it on" and "Find my size".

Step 4: Test it on your team

Have two or three people with different shapes run the scan on the same product. Check the suggested size against what your tailor would say in a fitting.

What does Find My Size cost?

Each size scan uses one measurement from your monthly plan.

Plan	Price	Notes
Free	$0	3 try-ons, 3 measurements and 5 invoices a month
Micro	$14/mo
Starter	$49/mo
Growth	$129/mo
Scale	$299/mo

Every paid plan has a 3-day free trial with no card required. Check the current ZeDaq.ai pricing for what each plan includes.

What can't a body scan do?

Be clear with your customers about the limits:

• It estimates, it doesn't tape-measure. A loose agbada or baggy top in the photo can hide the body's shape. Ask shoppers to wear fitted clothing.
• It only knows your chart. If your chart is wrong, the recommendation will be wrong too.
• It doesn't replace bespoke measuring. For made-to-order gowns, take a full set of measurements.

How do you get started?

Prepare your chart, enter it, add the feature to one or two best sellers, and test it. Once it suggests the sizes your team agrees with, roll it out across your range.

FAQs

Does the shopper need good lighting for the photo?

Good light helps. A full-length photo against a plain background, in fitted clothing, gives the most reliable result.

Can I use letter sizes and number sizes in the same store?

Yes. Each chart uses your own labels, so tops can use S, M, L while dresses use 10, 12, 14.

Does the scan work for menswear?

Yes. A tops chart for shirts and senator tops can use chest, and a bottoms chart can use waist and hips.

What if a shopper doesn't trust the suggestion?

Show your full size chart beside the recommendation. Shoppers can compare the suggested size with the measurements behind it.

Is the scan the same as virtual try-on?

No. Try-on shows the garment on the shopper's photo. Find my size gives a size recommendation. Both sit in the same window on your product page.
