Valentina

Valentina is open-source software for building and grading clothing patterns, with parametric sizing at its center. It best suits patternmakers who want designs to adapt to measurements and construction rules. Its focused 2D toolkit is a practical strength, but file-import and build-version limits matter when working across tools.

Overview

Valentina treats sizing as part of the pattern’s construction: measurements, increments, formulas, and rules can rearrange patterns automatically. That is useful when a pattern must respond systematically to different measurements, rather than being maintained as unrelated drawings. It supports 2D patternmaking and size grading, but not 3D garment simulation, textile design, or tech-pack creation.

The project began in 2013 with the stated goal of creating a multifunctional clothing-pattern construction and modeling program. The software is GPLv3+ licensed. Its FAQ says users may produce work of any kind, so commercial use is not restricted.

Key features

Pattern construction and output

Valentina exports SVG, PDF, PNG, OBJ, PS, EPS, and DXF. DXF export does not make it a two-way DXF workflow: importing DXF is unavailable because vector formats do not carry the information needed for Valentina’s pattern format. That limits its fit for users whose starting point is an existing DXF pattern.

Compatibility and build risk

Valentina supports .val files from Seamly2D, but the reverse compatibility is not supported. Teams moving files between the two should account for that one-way path. Development builds are testing snapshots; patterns saved in them may not open in the installed version or convert back. They are a poor choice for work that must remain dependable in a stable installation.

Pricing

Valentina’s pricing separates access to source and community help from access to current software binaries and developer support. The free option has meaningful limits for anyone who needs ready-to-install builds or official help.

Free is best for users comfortable with source code or historical versions who can rely on community support. Basic is the more practical choice for users needing current binaries and developer assistance; its development builds bring the compatibility caveat above. Premium is aimed at users who specifically need binaries for legacy platform versions or multi-size table files. Basic and Premium are billed at their stated monthly rates.

Platforms

Valentina supports Linux, macOS, and Windows. Stable downloads include a Linux AppImage; Windows packages for Windows 7+ 32-bit and Windows 10+ 64-bit; and macOS packages for 10.15+ Intel, 11+ Apple Silicon, and 12+ Universal. The listed package variants make OS and processor compatibility worth checking before choosing an installation.

Who it's for

Valentina is suited to patternmakers who value measurement-driven grading, want control over pattern construction, and can work within its 2D scope. The free plan can fit technically comfortable users who do not need current binaries or developer support. Look elsewhere if 3D garment simulation, DXF import, textile design, or tech-pack production is central to the job.

Pros and cons

• Parametric sizing: measurements, increments, formulas, and rules can drive pattern rearrangement, which supports systematic grading.
• Commercial freedom: the FAQ places no restrictions on the kind of work users produce.
• Broad export selection: SVG, PDF, PNG, OBJ, PS, EPS, and DXF cover several output needs.
• Restricted free access: Free omits current binaries, the manual, and developer support.
• One-way compatibility: Valentina opens Seamly2D .val files, but Seamly2D does not provide the reverse path.
• No DXF import or 3D simulation: these omissions rule it out for workflows that depend on either capability.
• Snapshot risk: development-build patterns may not return cleanly to the installed version.

Alternatives

Fashion Design Software is the broader category for comparing tools across the field.

Seamly2D is the closest alternative for users seeking free, open-source pattern software on Linux, macOS, or Windows; its .val compatibility with Valentina is one-way.

garment.dev is a web-based freemium option whose Hobby plan caps patterns, tech packs, moodboards, export resolution, markers, history, checkpoints, and editors.

Browzwear VStitcher is a paid alternative with a listed Freelancer plan at $75 a month, for one user and one site, with the newest version, AWS hosting, and community support.

PAD System is a paid option with a free trial and a Basic plan priced at $15 a year, available only on an annual subscription.

CLO 3D is a paid alternative with a free trial and student and individual plans.

Marvelous Designer is a paid option for Windows, macOS, and Linux with a cancelable personal monthly subscription.

Tailornova is a web-based alternative with a Personal plan at $29 a month, including monthly caps on technical-flat vector, MTM pattern, and PDF downloads.

Style3D Studio is another paid alternative for Windows and macOS.

Verdict

Choose Valentina if measurement-driven 2D patternmaking and grading are the priorities, especially if commercial freedom and access to source code matter. Its central advantage is pattern construction tied to sizing rules; its main drawbacks are the lack of DXF import and 3D tools, plus limited support and binaries on the free plan. For teams that depend on reversible file exchange, official support without paying, or 3D garment workflows, another tool is a better fit.
