About This Feature
Overview
Lock Aspect Ratio is a picture sizing feature in WPS Office for Windows Slides. It helps you resize an image without stretching or compressing it, which is useful when you need to keep the original width-to-height proportion while editing a presentation.
Core tasks include:
- Locking or unlocking picture proportions from the Picture Tools tab so you can control how an image scales.
- Changing either width or height while the other dimension updates automatically in proportion.
This is useful for slide layout work, cover slide design, product showcase pages, and other presentation editing tasks where image consistency matters.

Compare with Alternatives
| Dimension | WPS | Microsoft | Notion | Adobe | |
|---|---|---|---|---|---|
| Capability Summary | In WPS Slides, you can use the Lock Aspect Ratio checkbox in Picture Tools to control picture proportions. When you change width or height, the other dimension adjusts automatically in proportion. | Word lets you select or clear Lock aspect ratio in picture sizing settings and resize objects proportionally. | Google Docs provides Size & Rotation settings in All image options for image size, scale, and rotation adjustments. | Notion lets you resize images by dragging the sides of a media block and rearrange media blocks on the page. | Adobe Acrobat lets you resize images in a PDF by dragging image corners and supports proportional scaling. |
| WPS Advantages | Advantage: The control is placed directly in the picture sizing area, which fits slide editing workflows well. Distinct: When one dimension is edited, the other updates in proportion for faster layout adjustments. | Compared with WPS: Microsoft documents the feature mainly through general object sizing and format settings rather than a slide-focused picture tool workflow. | Compared with WPS: Google emphasizes image options in a sidebar, with less emphasis on a direct lock toggle in a presentation editing ribbon. | Compared with WPS: Notion focuses more on freeform page layout and drag-based resizing than on a presentation-oriented lock aspect ratio checkbox. | Compared with WPS: Adobe focuses on PDF editing, where proportional resizing is tied to image editing actions rather than a presentation picture tool entry. |

Overall Conclusion
Lock Aspect Ratio works well for presentation editing tasks that require stable image proportions. Compared with general document, page collaboration, or PDF editing tools, WPS keeps this control closer to the slide editing workflow and makes proportional picture resizing more direct.
