A sale doesn't just bring more traffic, it brings more shoppers who've never bought from you before and don't yet trust your fit.
With Kiwi Sizing, your size charts and recommendations sit right on the product page, exactly where sizing doubt turns into a bounced sale or a costly return. This checklist helps you make sure your sizing setup can handle the surge Labor Day brings.
Use it before your Labor Day sale goes live or when reviewing a sizing setup you plan to reuse for future sales.
1. Define the One Outcome Sizing Should Drive
Before checking charts, decide what "working" looks like for Labor Day.
☐ You can answer this in one sentence: "If sizing works during this sale, what should happen?"
Examples:
First-time Labor Day shoppers buy the right size on the first try
Return rate on sale items stays close to your normal baseline
Fewer pre-purchase questions come in about fit during the sale rush
New products added just for Labor Day launch with sizing already dialed in
Why this matters: This outcome tells you where to focus, new products, high-traffic bestsellers, or first-time buyer experience.
2. Make Sure Every Labor Day Product Has a Chart
Sale pushes often add new products or bundles, sizing coverage needs to keep pace.
☐ Every product included in the Labor Day sale has an assigned size chart — check with How to Find Products Without a Size Chart in Kiwi Admin
☐ New arrivals or Labor Day-exclusive items were not launched without sizing set up
☐ Charts are assigned at the correct level (product, variant, or collection) so nothing falls through — confirm with How to View Which Size Charts Are Linked to a Product
☐ Bundled or multi-item sale sets have sizing guidance for each component
Insight: A single unassigned product during a high-traffic sale can generate a disproportionate share of your returns.
3. Double-Check Chart Accuracy Before the Rush
Sale traffic amplifies small sizing mistakes into a lot of wrong orders.
☐ Measurements have been spot-checked against current inventory, not just past-season assumptions — if you're updating from a spreadsheet, see Can I Import a Sizing Table from Excel or Google Sheets into Kiwi?
☐ Unit display (in/cm) matches what your Labor Day audience expects
☐ Size recommendation logic has been tested with a few real measurements, not just default settings
☐ Any seasonal fit notes (e.g., "runs small," "true to size") are current and visible — if a last-minute edit goes wrong, you can undo it with How to Perform a Rollback for a Size Chart in Kiwi?
Insight: Shoppers rushing through a sale won't read fine print, they'll trust the chart or bounce.
4. Make Sizing Easy to Find in a High-Traffic Moment
If a shopper has to hunt for it, they'll guess instead, or leave.
☐ Size chart link or widget is visible without scrolling past the buy button — understand placement behavior in How Kiwi Works on the Product Page (Understanding What's Happening Behind the Scenes)
☐ Sizing guidance displays correctly on mobile, where most sale traffic lands
☐ Chart doesn't visually clash with your Labor Day countdown, banner, or gift-offer messaging — for exact placement control, see How to Position the Size Chart Link Above Variants or Next to "Size" on a Product Page?
☐ Recommendation tool (if used) loads quickly under expected sale traffic — if speed is a concern, check Can I make the size chart load faster?
Insight: During a sale, a shopper's patience for finding sizing info is shorter than usual, not longer.
5. Prepare for First-Time Buyers Specifically
Labor Day sales often bring people who've never bought from you before.
☐ Sizing language avoids brand-specific shorthand a new customer wouldn't know
☐ A simple "how to measure" reference is available, not just a size number chart
☐ Common cross-brand comparisons are addressed if relevant to your category — consider turning on How to Enable and Customize the Size Comparison Chart
☐ Support team knows the top 2-3 sizing questions they're likely to get during the sale
Insight: A loyal customer already trusts your fit; a first-time Labor Day shopper is deciding whether to trust you at all.
6. Plan for the Return Conversations Before They Happen
Even great sizing can't prevent every return, but it can make them cheaper.
☐ Post-purchase sizing confirmation (email or on-site) is active for sale orders
☐ Support team has a fast path for exchanges tied specifically to sizing
☐ You know how you'll track whether returns spike on any specific Labor Day item — set this up with Can I View Analytics for Size Chart Usage in My Shop?
☐ Sizing data from the sale will be reviewed, not just filed away
Insight: The goal isn't zero returns, it's making sure the ones that happen teach you something for next time.
7. Ask One Smart Question After the Sale
Simple review beats a long retro.
☐ "Which products had the highest sizing-related returns during Labor Day?"
☐ "Did first-time buyers size differently than repeat customers?"
☐ "What chart or wording change would prevent next season's mis-sizes?"
Insight: One honest question after Labor Day makes your next big sale's sizing setup sharper.
Final Check
Before your Labor Day sale goes live, ask yourself: "If I were a first-time shopper buying this on sale, would I know exactly what size to order?"
If the answer is yes, your sizing setup is ready for the rush.
