The best spec sheet software for exporters: SizeMarker, Microsoft Excel/Word, Canva, Photopea, Affinity and Visme, plus Specright for enterprise spec data. SizeMarker is the only one built for dimension-accurate spec diagrams on product photos.
1SizeMarkerOur pick
Best for dimension-accurate spec diagrams
A tool built specifically for the visual half of a spec sheet: dimension lines that snap to the product edge on a real photo, bilingual spec labels, callouts and contour outlines, exported at Alibaba, 1688 or Amazon image sizes. AI assists with placement; the numbers stay accurate because the geometry is deterministic.
Pros
- Dimension callouts tied to the actual product photo — snap-to-edge, scale-aware, resize-proof
- Bilingual (e.g. English + Chinese) spec labels in a single element — no re-layout for overseas buyers
- Marketplace export presets (Alibaba 1000², 1688 800², Amazon 2000²)
- Runs in the browser, free to start
Cons
- Focused on spec diagrams — for long text documents you still pair it with a doc tool
- A newer tool than the incumbents below
- Price
- Free · Pro $12.90/mo · Enterprise $19.90/seat/mo
- Best for
- Exporters and B2B suppliers whose buyers need to see exact dimensions before ordering.

The incumbent for spec tables
The default office suite. Spec tables — SKU, materials, net/gross weight, carton dimensions, MOQ — are exactly what Excel grids and formulas are for, and every factory, buyer and freight forwarder can open the file.
Pros
- Zero adoption friction: everyone in the trade chain already opens .xlsx/.docx
- Formulas handle packing math (units per carton, CBM, gross weight) automatically
- Microsoft’s template hub offers document starting points
Cons
- No way to draw dimension callouts anchored to a product photo — text boxes drift when anything reflows
- Output is a document, not a listing-ready image; no marketplace export sizes
- Price
- Microsoft 365 subscription · free web options
- Best for
- The tabular data half of a spec sheet — the tool every exporter already owns.
3Canva
Fast, good-looking one-pagers
The mass-market design tool. Drop in a product photo, pick a template, and a decent-looking product one-pager comes together quickly — though its template universe is social-and-marketing-first, not trade-document-first.
Pros
- Huge template library and a genuinely usable free tier
- Easy branding and team collaboration on paid plans
Cons
- Arrows and lines are freehand decorations — no measurement ties a line to a real size
- No spec-sheet or export-trade template category; no marketplace export presets
- Price
- Free tier · paid plans
- Best for
- Exporters who want a pretty product one-pager fast and will eyeball the dimension arrows.
4Photopea
Free, manual photo annotation
A free, browser-based Photoshop-style editor. You can annotate directly on the product photo with lines, shapes and text on layers — every measurement placed and typed by hand.
Pros
- Free, nothing to install, opens PSD/AI/Sketch/SVG files
- Real pixel-level editing directly on the product photo
Cons
- Dimension lines are hand-drawn pixels — no scale, no dual-unit labels, redo everything on resize
- No spec-sheet templates, no batch or platform export presets
- Price
- Free (ad-supported)
- Best for
- Budget-zero exporters trading time for money on one-off diagrams.
5Affinity (by Canva)
Pro-grade precision, now free
Professional vector, photo and layout software, free for individuals. Precise anchor points and curves make it the closest free stand-in for Illustrator-grade control — a polished multi-page spec catalog is doable end-to-end.
Pros
- True professional precision: scalable vector shapes with exact anchor points
- Vector + photo + page layout in one app, unbeatable price for the capability class
Cons
- Dimension callouts are still manual line-and-text constructions, not measurement objects
- Designer-level learning curve; desktop install required; no trade templates or platform presets
- Price
- Free for individuals
- Best for
- Exporters with an in-house designer producing high-polish spec catalogs.
6Visme
Data-widget one-pagers
An all-in-one visual content platform whose template library includes reports, proposals and one-pagers. Charts, graphs and comparison tables handle the numbers half of a sales-facing spec sheet well.
Pros
- Strong chart/table widgets for the data half of a spec sheet
- Brand kit and approval workflow on paid tiers for consistent sales collateral
Cons
- Infographic-oriented — no dimension annotation tied to product photos
- Templates skew marketing rather than technical; no export-trade presets
- Price
- Free tier · paid plans
- Best for
- Sales-facing product one-pagers where charts matter more than measured diagrams.
7Specright
Enterprise spec data management
A specification data management (SDM) platform — the system of record for formulas, packaging, BOMs and supplier collaboration at Fortune-500 scale. Genuinely "spec software", but it manages spec data; it does not draw spec diagrams.
Pros
- Governed, auditable spec data across hundreds of SKUs with supply-chain traceability
- Supplier collaboration workflows built for exporter-buyer spec exchange
Cons
- No visual dimension annotation on product photos at all — output is structured data, not a buyer-facing image
- Quote-based enterprise pricing and sales cycle, out of reach for small trading companies
- Price
- Quote-based (enterprise)
- Best for
- Mid-to-large manufacturers who need a governed spec system of record.
Side-by-side comparison
“Dimension diagrams on photos” means the tool ties drawn lines to real measurements on the product image. Document and design tools can hold the spec table, but the diagram numbers are typed by hand.
FAQ
What software do exporters use to make spec sheets?
Most exporters combine two tools: Excel or Word for the spec table (materials, weights, carton and packing data) and a visual tool for the dimensioned product image. SizeMarker covers the visual half with measurement-accurate dimension callouts; general design tools like Canva or Photopea can draw the lines, but every number is typed by hand.
Can I make a product spec sheet in Excel?
Yes — for the table half. Excel is excellent for SKU data, materials, net/gross weight and packing math. What it cannot do is draw dimension callouts anchored to a product photo: text boxes float free and drift when anything reflows, so the diagram half needs a dedicated tool.
What should an export spec sheet include?
At minimum: product dimensions (width × depth × height, with tolerances where they matter), materials, weight, packaging and carton dimensions, and order details like MOQ. Put the key dimensions on the product photo itself — buyers read a dimensioned spec image far faster than a table, and standard sizes are collected in our dimension reference guides.
Do I need CAD software to make an export spec sheet?
No. CAD is for engineering drafting — far heavier than a buyer-facing listing needs, and the output reads like a blueprint, not a product image. A dimension annotation tool produces a spec diagram buyers actually understand, in minutes.
How do I put dimensions on the product photo itself?
Use a measurement-aware annotation tool: draw dimension lines whose endpoints snap to the product edge, add a bilingual size label, then export at your marketplace’s image size. We compared the options in 7 best tools to add dimensions to product photos.
