Calculate print pixel needs from scarf, shawl and fabric panel sizes; see aspect ratio and plan upscale for low-resolution sources. A free B2B helper for textile digital print teams.
Panel presets
Required pixels
Upscale from your file
Panel pixel prep before pattern generation
Lock target px in the tech pack
Paste the width × height px values from this tool into PO approval notes. Match Generator output to the panel aspect ratio — wrong ratios delay sample approval.
Plan repeat size at print DPI
After panel px targets are clear, lock repeat cm/inch with the Rapport Calculator. Size seamless repeats in the Generator against panel width.
Generate art after panel ratio lock-in
Once target px and upscale factor are clear, create panel-safe designs in AI Pattern Studio with the same palette. Copy the upscale factor from this tool when needed.
Keep the width × height px values from this tool identical in your tech pack, RIP, and vector file. Copy size into approval notes — it clarifies panel DPI targets before vectorizing.
Preserve aspect ratio in source art
Source files that do not match the panel aspect ratio break vector paths. Align source px dimensions to this tool’s ratio; upscale toward target px first when needed.
Vectorize at 300+ DPI targets
Close-up fashion panels often need 200–300 DPI in digital textile print. After validating target px here, move art into Vectorizer Studio; read the guide for the SSIM ≥ 0.85 threshold.
Mockup sign-off after panel pixel target is locked
Lock width × height px and DPI line on the tech pack
Paste the required pixel, megapixel and aspect ratio lines from this tool into sample approval notes. Wrong panel scale causes motif clipping or empty margins in mockups.
Validate scarf/shawl template fit in Mockup Studio
Panel width/height and aspect ratio should be evaluated together — square scarf and rectangular shawl templates need different crops. Match scale/rotate steps in the mockup guide to this px line.
Open the print PO after buyer approval
After mockup visual sign-off, move the px line from this planner into production; audit mockup credits/cost on Account History.
Lock required px and upscale factor on the tech pack
Paste the width × height px, megapixel and upscale factor lines from this tool into sample approval notes. When source file dimensions are below target px, upscaling is required — validate when the factor is above 1× before PO signature.
Compare source pixels vs target DPI line
Save source width × height alongside the required px line before upscaling. The 16x pipeline caps at 16K px output — validate 300+ DPI at final print size before upscaling low-source drafts.
Move approved panel art into Upscale Studio
Scarf/shawl panel files upscale best with tile-safe mode. Max output side is 16,384 px — read the Upscale quality guide for the SSIM ≥ 0.85 threshold; audit upscale credits/cost on Account History.
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.
