Upscale from your file

Digital textile viewing distance often allows 150 DPI; close-up fashion panels may want 200–300 DPI. Use Sapphire Upscale when the factor is above 1×.

Why panel planning matters in digital textiles

In digital textile printing, file pixel size is tied to physical panel dimensions and target DPI. A 90×90 cm scarf at 300 DPI is ~113 megapixels; a 70×183 cm shawl needs a much wider canvas. Aspect ratio directly affects pattern cropping and seamless repeats.

Professional B2B panel planning has three layers: (1) physical panel → pixel conversion (this tool), (2) repeat and seamless validation — Rapport Calculator and Seamless Checker, (3) production cost and AI upscale — Fabric Cost Calculator and Sapphire 16× Upscale. For post-shrink effective panels, use the Shrinkage Calculator first.

SapphireSC (sapphiresc.com) is the B2B AI platform from İlçel Sapphire Tekstil (Bursa): seamless pattern generation, 16× upscale, vectorization and mockups. Free utilities support organic discovery; production workflows continue in the AI Pattern Generator and Vectorizer.

Digital print practices (reference)

  • 150 vs 300 DPI — strike-offs at 150; scarf/shawl production typically 300
  • Megapixels — 90×90 cm @ 300 DPI ≈ 113 MP; directly affects RIP memory and upscale cost
  • Aspect ratio — artwork ratio mismatch causes cropping or gaps
  • Upscale factor — source px ÷ target px; 16× Upscale scales up to 16× per axis
  • Use the Rapport Calculator for repeat tile counts; the DPI Calculator for mesh/DPI validation

Quick reference formulas

  • Pixels = (cm ÷ 2,54) × DPI
  • Aspect ratio = panel eni ÷ panel boyu
  • 90×90 cm @ 300 DPI ≈ 10,630 × 10,630 px
  • 70×183 cm @ 300 DPI ≈ 8,268 × 21,614 px

Frequently asked questions

How many pixels for a 90×90 cm scarf at 300 DPI?

About 10,630 × 10,630 pixels (≈113 MP). Formula: inches = cm ÷ 2.54; pixels = inches × DPI. This tool computes that from panel size and DPI automatically.

Why does aspect ratio matter?

If your artwork ratio does not match the fabric panel, you get cropping, gaps or distortion. Use presets like 1:1 scarf or 70×183 cm shawl for quick checks.

How much upscale does a low-res file need?

Upscale mode compares source pixels to the target panel at your DPI and shows the limiting factor (e.g. 5×). Sapphire 16× Upscale can close that gap.

What DPI should I use for digital textile print?

Strike-offs and quick proofs often use 150 DPI; production scarves, shawls and apparel panels typically target 300 DPI. This tool accepts any DPI and shows megapixels — validate mesh and effective DPI in the DPI Calculator.

How do megapixels relate to upscale need?

Megapixels = (width px × height px) ÷ 1,000,000. If your source file is smaller than the target panel at your DPI, upscale mode shows the limiting factor (e.g. 5×). Sapphire 16× Upscale closes gaps up to 16× per axis.

What is the difference between panel size and repeat tile?

Panel size is the physical fabric piece (e.g. 90×90 cm scarf). Repeat tile is the artwork unit that tiles across the panel. Use the Rapport Calculator for tile counts; this planner focuses on total panel pixel dimensions.

Can I reverse-plan from pixel dimensions to cm?

Yes — reverse mode converts pixel width/height + DPI back to physical cm/inches. Useful when a RIP exports fixed pixel sizes and you need to confirm they match the tech-pack panel.

Is this panel planner free?

Yes. It runs entirely in your browser with no account required. AI pattern generation, upscale and vectorization require Sapphire credits or a plan.
