Overview

Astro Scale helps Roblox developers convert finished interfaces between Scale and Offset, reclass selected UI objects, align interfaces, handle supported UI components and run a final Perfect Scale pass before shipping.

Astro Scale is a Roblox Studio plugin built for developers who want to make finished interfaces responsive without manually rebuilding every UI value.

Scale and Offset tools

Convert Size and Position between Scale and Offset, or use the dedicated X and Y controls when only one axis should change. Auto Size and Auto Position can keep selected UI in the mode you prefer while you continue working.

Perfect Scale

Select a completed ScreenGui and run Perfect Scale for a final responsiveness pass. Astro Scale recursively reviews the interface, cleans up supported Scale/Offset values, handles supported UI components, preserves working setups where possible, and avoids unnecessary repeat conversions.

UI tools

Astro Scale also includes Reclass, Figma-style alignment controls, AnchorPoint tools, text scaling, aspect-ratio utilities, Include Children, Auto Anchor, persistent settings, Undo/Redo support and compact conversion notifications.

Reclass

Use Reclass to change selected UI objects to another supported class. Type a class name, use autocomplete to confirm the intended result, and press Enter to apply it to the current selection.

Supported components include UIPadding, UICorner, UIStroke, UIGridLayout, supported layout padding and manually controlled ScrollingFrame.CanvasSize.

Every UI instance modified by Astro Scale receives:

AstroScale = "By GoldAstro"
