Honest Size Charts

Shopify app · Online Store 2.0

Shopify size charts in a popup — flat fee, theme-safe.

Assign charts by product, collection, tag, or vendor on every plan. Show them in a popup via a theme app block — no code edits. Pro is $8.99/mo for unlimited charts; pricing never follows your order count.

Measure twice. Chart once. Return less.

Tired of size chart apps that…

Flat Pro pricing, a free plan with no watermark, and a theme app block you can remove without editing code.

How it works

Three steps from blank chart to a “Size guide” link on your product page.

Three steps. Zero theme surgery.

  1. Step 1

    Build your chart

    Use the grid editor or upload an image. Image charts save to Shopify Files.

  2. Step 2

    Set assignment rules

    Choose which products, collections, tags, or vendors get each chart — on Free and Pro.

  3. Step 3

    Add the theme block

    Place the app block in the theme editor on your product template, then check mobile and desktop.
