Size Chart Creation & Management

SmartSize provides powerful tools to create and organize professional size charts for your entire product catalog:

• Professional Size Chart Builder - Build custom size charts using an easy spreadsheet-like editor. Add rows and columns, input measurements, and organize your sizing information exactly how you need it.

• Ready-Made Templates - Start quickly with pre-built size chart templates for clothing categories like shirts, dresses, shoes, jackets, and more. Includes special templates for popular print-on-demand services like Printful, so you can launch faster.

• Multiple Size Charts - Create unlimited size charts (on paid plans) for different product categories. Organize your entire catalog with charts specific to each product type, from activewear to formal wear.

• Multi-Tab Size Charts - Add multiple tabs within a single size chart to show different measurement systems, fit guides, or size variations all in one place. Perfect for stores that want to provide comprehensive sizing information without overwhelming customers.

Product & Collection Linking

Connecting your size charts to products is straightforward and flexible:

• Link Charts to Products - Connect any size chart to one or multiple products. Your customers will see the relevant size chart on each product page automatically, right when they need it.

• Link Charts to Collections - Apply a single size chart to an entire collection of products at once. Perfect for product categories that share the same sizing, saving you time managing large catalogs.

• Easy Product Management - View all products with or without size charts in one dashboard. Quickly find products that need a size chart assigned to them, so nothing slips through the cracks.

Measurement Help for Customers

Help your customers measure accurately to find their perfect fit:

• Measurement Instructions - Add step-by-step instructions to help customers measure themselves correctly. Clear guidance reduces returns by helping shoppers understand exactly how to take their measurements.

• Image Gallery - Access SmartSize’s built-in library of measurement images or upload your own custom images to show customers exactly where and how to measure. Visual guides are especially helpful for items with unique fits.

• True Fit Scale Bar - Show customers if your products run small, normal, or large compared to standard sizing. Add a helpful visual scale with custom labels and tooltip explanations to manage fit expectations upfront.

Automatic Unit Conversion

Make your size charts work for international customers:

• CM to Inches Toggle - Let customers switch between centimeters and inches with one click. SmartSize automatically calculates and displays conversions in real-time, so you only need to maintain one set of measurements.

• Flexible Conversion Settings - Control which columns convert and set custom rounding rules to display measurements exactly how you want them. Perfect for when precision matters or when you want cleaner numbers.

Multi-Language Support

Serve global customers in their own language:

• Translate Your Size Charts - Create size charts in multiple languages for international stores. Works seamlessly with Shopify’s Translate & Adapt app to maintain consistency across your store.

• Auto-Translated Button Labels - Your size chart button labels and units can be automatically translated based on your customer’s language, creating a seamless localized experience.

Design & Customization

Make your size charts look like they belong in your store:

• Match Your Brand - Customize colors for headers, fonts, zebra lines, and focus states. Make your size charts look like they’re built into your theme, not added as an afterthought.

• Button Style & Placement - Display your size chart button as a floating button or inline with your product information. Pick the style that fits your store layout and matches your customer’s shopping flow.

• Custom Icons & Labels - Select from multiple button icons and write custom button labels. Make it clear and inviting for customers to check sizing with text that matches your brand voice.

• Adjust Size Chart Width - Control how much space your size chart takes up on desktop screens. Choose from extra small to maximum width options to match your theme’s layout.

• Header & Footer Text - Add helpful text above or below your size charts to provide additional context, care instructions, or sizing notes that apply to all your measurements.

• Border & Corner Radius - Fine-tune the visual appearance with custom borders and corner radius settings to match your store’s design language, from sharp and modern to soft and friendly.

Display Options

Optimize how your size charts appear across all devices:

• Desktop & Mobile Layouts - Choose different layouts for desktop and mobile views. Optimize how your size chart content is arranged on different screen sizes for maximum readability.

• Popup Animations - Select from various animation styles when your size chart opens (grow, slide, zoom, fade) for a polished user experience that feels native to your store.

• Position Control - Place your size chart popup on the left, center, or right of the screen to match your store’s layout preferences and avoid blocking important product information.

• Fixed First Column - Keep the size column visible while customers scroll horizontally on mobile devices, making it easier to compare measurements without losing track of which size they’re looking at.

Bulk Operations

Manage multiple size charts efficiently:

• Manage Multiple Charts at Once - Select multiple size charts and activate them, set them to draft, or delete them all with a single action. Essential for stores with seasonal catalogs or frequent product updates.

• Duplicate Charts - Quickly copy an existing size chart to create variations for similar products without starting from scratch. Perfect for when you need slight modifications across different product lines.

• Search & Filter - Find specific size charts quickly by searching by name, status, or language. Sort by date, status, or type to stay organized as your chart library grows.

Publishing & Status Control
