# Size & Fit Guidance with BuyScout® AI Store Agent Help shoppers choose a suitable size using published measurements, product-specific guidance, and their stated fit preferences. ## 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. 1. **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. 2. **Sizing changes across products** The shopper usually wears one size, but the current product uses different measurements, proportions, fit guidance, or market-specific labels. 3. **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. 1. **Resolve the exact item** The AI Store Agent identifies the relevant product, variant, market, and published sizing source before comparing options. 2. **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. 3. **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. **Outcome** The 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. 1. **Product-specific size charts** BuyScout® automatically reads shopper-facing size ranges and fit guidance from the relevant product page. 2. **Clear measurement labels** BuyScout® uses documented units, measurement types, and product-specific fit notes to distinguish body measurements from garment or product measurements. 3. **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 **Does Size & Fit Guidance require separate setup?** BuyScout® automatically uses sizing information available in Shopify and across the store website. Merchants can optionally add product-specific guidance in BuyScout® Dashboard. **Can BuyScout® account for relaxed, close, or layered fit?** BuyScout® uses a shopper's stated fit preference when the product's chart or fit notes support a meaningful comparison. BuyScout® explains the trade-off without presenting a preference as a measured fact. **Does BuyScout® guarantee that a recommended size will fit?** No. BuyScout® explains the best-supported option from published measurements and the shopper's stated preference, while making chart boundaries and uncertainty clear. **What if a shopper does not know their measurements?** 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. **Can BuyScout® reuse sizing from another product or brand?** 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. **What happens when sizing information is missing or conflicts?** 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.
