Compare Shore hardness with a softness illustration
Compare matching rubber pads being pressed. This is a tactile illustration, rather than a hardness-testing instrument.

Conditions
A and D are separate scales. Compare relative impressions within one scale; no conversion is performed.
Visual preview
Ready2D · side-view deformation illustration
Deformation is an illustrative effect, not a calculation of displacement, pressing force or time. Material and thickness can change the feel even at the same hardness.
How to read this view
How should I read this?
Add a comparison to place matching pads side by side. Within one scale, lower readings are illustrated on the softer side and higher readings on the harder side. This does not predict an indentation in millimetres.
How do Shore A and D differ?
A and D are different test scales, commonly used for softer rubber and harder plastics respectively. A50 and D50 are not equivalent. The illustrated deformation cannot compare across scales.
Will this predict the feel of a real object?
This is an introduction to imagining relative hardness. Actual feel also depends on material, thickness, shape, temperature and how it is pressed; evaluate physical samples when selecting a product.
