One line of HTML

Paste one script or iframe snippet — no API keys, no maintenance.

Helps your readers

Let visitors check whether their bag fits without leaving your article.

Example placements

The widget works best when it appears at the exact moment readers are comparing a bag, an airline, or a fare rule.

Airline baggage guide

Place the checker after a Ryanair, easyJet, Wizz Air, or Delta bag-size paragraph so readers can test their exact bag before buying.

Best anchor: “Check your bag size before the gate.”

Packing list or gear review

Add the compact link below a suitcase/backpack recommendation so the buying step stays useful, not pushy.

Best anchor: “Will this bag fit your airline?”

Forum FAQ or newsletter

Use the text snippet when iframes are blocked. It still gives readers a direct tool and gives you measurable UTM traffic.

Best anchor: “Free carry-on size checker.”

Copy-paste snippets

Pick the format your CMS allows. Each snippet is UTM-ready; replacepartnerwith your site name before publishing.

Auto-resizing widget

Recommended for travel guides. Replace `partner` with your site name; height adjusts automatically.

<script
  async
  src="https://carrysizer.com/embed.js"
  data-publisher="partner"
  data-campaign="article_widget"
></script>

Iframe fallback

Use when your CMS blocks scripts. Replace `partner` with your site name.

<iframe
  src="https://carrysizer.com/embed/check/?utm_source=partner&utm_medium=embed&utm_campaign=article_widget"
  width="100%"
  height="560"
  style="border:none;border-radius:12px;"
  title="Carry-On Bag Fit Checker"
  loading="lazy"
></iframe>

Compact text link

Use when your CMS blocks iframes, or below product recommendations in best-bag lists.

<a
  href="https://carrysizer.com/check/?utm_source=partner&utm_medium=referral&utm_campaign=bag_fit_checker"
  target="_blank"

Usage guidelines

Keep the built-in “Powered by CarrySizer” link visible inside the widget.
If you use the text link or badge, link to the checker or this widget page with your own UTM source.
Do not present CarrySizer as legal or airline-official advice; rules can change and travellers should verify before flying.
Do not remove affiliate disclosures on pages where your own product links appear.

Outreach target list

Start with pages where a bag-size utility solves a repeated reader question.
