How does BuyScout® help shoppers choose a size?

BuyScout® AI Store Agent uses the relevant product's published size chart, measurements, fit notes, available variants, and the shopper's stated preferences. It can ask for a decisive measurement or intended fit, then explain the supported options and trade-offs.

Sizing decisions that need guidance

A size selector becomes more useful when shoppers can connect its labels to their own measurements, preferences, and intended use.

Between two listed sizes

A shopper falls near a chart boundary and wants to understand how a closer or roomier option relates to the published measurements.

Sizing changes across products

The shopper usually wears one size, but the current product uses different measurements, proportions, fit guidance, or market-specific labels.

Fit depends on how it will be worn

Layering, compression, mobility, or a relaxed versus close fit can change the preferred option when the shopper states that preference.

From size question to grounded guidance

BuyScout® keeps the answer tied to the exact product and asks only for information that can change the choice.

Resolve the exact item

The AI Store Agent identifies the relevant product, variant, market, and published sizing source before comparing options.

Ask for the deciding input

BuyScout® can ask for a measurement, usual size, fit preference, layering need, or intended use when that detail changes the guidance.

Explain the supported choice

The response connects the shopper's input to the published chart or fit notes and makes any boundary, trade-off, or uncertainty clear.

A shopper is between two jacket sizes

SummitArc 3L Shell

$179
Shopper:

I'm choosing a SummitArc 3L Shell. Should I get M or L if I want room for a sweater?

BuyScout®: Checking the size chart and layering guidance
BuyScout®:

The size chart lists M for a 38-40 inch chest and L for 40-42 inches. What's your chest measurement?

Shopper:

40 inches, and I prefer a relaxed fit.

BuyScout®:

Both ranges include 40 inches. The published chart supports either at the boundary; L is the roomier choice for your stated layering preference.

OutcomeThe guidance uses the product's own chart, asks one decisive question, and explains the trade-off without guaranteeing fit.

Product information behind better fit guidance

BuyScout® works automatically from Shopify and store content. Clear, product-specific sizing information makes the guidance more precise.

Product-specific size charts

BuyScout® automatically reads shopper-facing size ranges and fit guidance from the relevant product page.

Clear measurement labels

BuyScout® uses documented units, measurement types, and product-specific fit notes to distinguish body measurements from garment or product measurements.

Current variant availability

BuyScout® uses current Shopify size options and availability to keep unavailable variants out of its guidance.

How Size & Fit Guidance works automatically

Size & Fit Guidance starts from connected product and storefront information without separate skill configuration.

  1. Read product sizing information

    BuyScout® automatically reads Shopify product and variant data, product pages, size charts, measurement notes, and other relevant store content.

  2. Understand the shopper's preference

    BuyScout® uses stated measurements, usual size, intended use, and fit preference, asking a short follow-up only when it changes the answer.

  3. Compare and explain the options

    BuyScout® relates the shopper's input to the exact product's published guidance and explains the supported choice or trade-off.

  4. Optionally add merchant guidance

    Merchants can optionally add product-specific fit notes, tailor the conversation, and test representative products and edge cases in BuyScout® Dashboard.

Size and fit boundaries

BuyScout® makes sizing decisions clearer while preserving the uncertainty in published measurements.

  • No guaranteed fit BuyScout® can explain the strongest documented option, but body shape, comfort, and product variation prevent a guaranteed result.
  • No inferred body measurements BuyScout® uses shopper-provided measurements and documented product information instead of guessing body measurements or shape from behavior, images, or unrelated profile information.
  • No chart transferred between products BuyScout® keeps sizing guidance scoped to the product, variant, brand, and market described by the store.

Frequently asked questions

BuyScout® automatically uses sizing information available in Shopify and across the store website. Merchants can optionally add product-specific guidance in BuyScout® Dashboard.

No. BuyScout® explains the best-supported option from published measurements and the shopper's stated preference, while making chart boundaries and uncertainty clear.

BuyScout® can ask about the shopper's usual size, intended use, layering needs, or preferred fit, then explain what the published product guidance supports without inventing a measurement.

BuyScout® uses the exact product's sizing information. A familiar size in another product or brand can add shopper context, while the current chart remains controlling.

BuyScout® states which detail cannot be confirmed and asks for useful clarification when possible. If the shopper still needs a decision that BuyScout® cannot fulfill, it can notify store support as an edge case.
