T-Shirt & Apparel Design Tool for Your Online Store
Add a t-shirt design tool to your online store. From custom tees to full sportswear collections, shoppers design in a multi-view editor with realistic garment mockups that turn browsers into buyers.
Built for the apparel industry
Multi-view design editor
Customers design the front, back, left sleeve, right sleeve, and collar, each with its own canvas, layers, and print area. Switch between views instantly without losing work.
Realistic garment mockups
Designs render live on photographic or illustrated garment mockups so shoppers see exactly how their artwork sits on the fabric, including folds, seams, and color variations.
Size-specific design scaling
Automatically adjust print dimensions based on garment size. A design placed on an XL tee scales proportionally for a Small, so placement stays consistent across your entire size run.
How Sigmira helps your apparel business
Sell more with realistic previews
A shopper who can see their design on the actual garment buys with more confidence than one squinting at a flat canvas. Sigmira renders every edit in real time on your product photography, so the preview matches the finished piece. Fewer orders come back, because what arrived is what they saw.
Handle complex apparel layouts
Apparel is not a single flat surface. Sigmira lets you define independent print areas for front, back, sleeves, pockets, and labels. Each area has its own size constraints, layer stack, and export file. Your production team receives separate, properly sized artwork for every print location on the garment.
Scale from one-offs to team orders
One custom hoodie or a full team kit with names and numbers: Sigmira handles both. Variable data fields let buyers enter per-unit text like player names and jersey numbers, and the system generates individual production files for every item in the order.
Everything you need in one plugin
The same powerful feature set in every Sigmira plan, tailored to your workflow.
Drag-and-drop design editor
Give your shoppers a real-time product customizer on your storefront. They add text, upload high-res images or start from a pre-made template, and watch an instant, pixel-perfect preview as they go.
Multi-view product designs
Give your customers creative freedom across multiple design angles. Each view is isolated, with its own print layers and design controls, so the front of a shirt never interferes with the back.
Smart pricing engine
Set the pricing options that fit your products: per text, per character, per view, even per mm². Customers watch a live cost preview while they design, so the price at checkout never surprises them.
Production-ready file export
No more manual file preparation. Sigmira renders every design server-side and produces high-DPI PNG, JPG and production-ready PDF files the moment an order is placed.
Built into WooCommerce
Sigmira runs inside WooCommerce today. It supports multi-variant products, updates cart thumbnails with the customer's design and attaches print-ready files to the order itself. Shopify support is on the way.
Built for mobile
Over half of your customers shop on their phones, so the editor is built for touch first: pinch-to-zoom, drag handles, controls that fit under a thumb. On a desktop it works just as well.
Frequently asked questions
Common questions about using Sigmira for apparel.
Can customers design on multiple views of the same garment?
Yes. Sigmira supports unlimited design views per product. Most apparel stores set up front, back, and sleeve views, but you can add any angle you need. Customers switch between views in a single click, and each view maintains its own canvas and layers.
Does the design scale automatically for different garment sizes?
Sigmira supports proportional scaling rules per product. You define the base design area on your reference size, and the system adjusts print dimensions for every other size in the run so artwork stays proportionally consistent from XS to 3XL.
Can I offer name and number personalization for team orders?
Yes. Variable data fields let customers enter different text for each unit in a bulk order. Sigmira generates a separate production file per unit with the correct name, number, or other personalized data already applied.
What garment mockup formats does Sigmira support?
You can upload any high-resolution image as a product mockup: flat lays, ghost mannequin photos, or lifestyle shots. Sigmira overlays the customer design onto the mockup in real time, and you control the overlay position, rotation, and blending mode.
