Our verdict on Sizer
Sizer is a Windows desktop utility for people who need application windows to open or stay at consistent sizes and positions. Its menu offers predefined dimensions, while users can configure additional sizes and positions. That makes it relevant to web designers, technical authors, and developers who benefit from repeatable window arrangements, as well as anyone who wants precise manual adjustments. It is freeware and can run from an installer or a portable archive.
Sizer 4.0 extends the basic resize-and-reposition workflow with hotkeys, formulas, and macros for laying out multiple application windows. Users can organize menu options into groups and import or export configuration settings. During interactive resizing, Sizer can display window dimensions and snap movement to a configurable grid. These features focus on precision and repeatability rather than broad automation: choose Sizer when exact geometry and reusable arrangements matter more than a wider set of window-management capabilities.
The fit is deliberately narrow: Sizer runs on Windows, and its published support channel is documentation. The vendor describes Sizer 4.0 as a preview build, so buyers who need a finished, broadly scoped window manager may prefer an alternative. For solo users and small teams working on Windows, its freeware model and portable option keep adoption straightforward; people who need cross-platform support or more extensive management features should look elsewhere.
