Frequently Asked Questions
Choose "Database Objects" to search and select from our verified database of 70+ devices and everyday objects, or choose "Custom Dimensions" to enter arbitrary width and height values. The tool renders both objects to scale with overlay or side-by-side views, and you can drag objects freely in overlay mode.
Yes! Switch to "Custom Dimensions" mode and enter the width and height of any object in millimeters, centimeters, or inches. You can also pick a shape (rectangle or circle) and a custom color.
Overlay mode stacks both objects on top of each other at the same scale, so you can see exactly how much larger one is than the other. You can drag either object to align them. Side by Side mode places them next to each other for a traditional comparison view.
The tool supports millimeters (mm), centimeters (cm), and inches (in). In Custom Dimensions mode you can switch units at any time. All measurements are converted automatically.
The comparison is mathematically accurate. Both shapes are rendered at the exact same scale, so the proportions you see on screen match real-world proportions exactly. No distortion, no exaggeration.
