Yes—absolutely. Siemens has historically distributed Sizer as freeware. You do not need a paid license, a dongle, or an activation key. The software is provided at no cost to support engineers in designing systems using Siemens products.
However, there is a critical nuance: Siemens no longer hosts Sizer 323 directly on its main public download page. The company encourages users to adopt the newer Sizer 2025 tool. But because Sizer 323 is still needed for legacy support, Siemens occasionally makes it available through:
- Archived product support pages
- Legacy software vaults (requires free registration)
- Technical support request files
