Grain of sand vs Salt crystal
What are they, and what does the difference actually look like?
Two things. One honest scale.
Meet the pair
What these two things are
Salt crystal
A salt crystal is a small, naturally occurring or manufactured piece of sodium chloride used in food and industry.
300 µmCharacteristic sizeThe diameter of Grain of sand is about 1.67 times the characteristic size of Salt crystal.

Measurements, assumptions & sources +
Grain of sand
Separate illustrative measurements: 0.5 mm across; 1 mg mass. Mineral and shape vary.
Defined examples — our methodology
The marked diameter is calibrated. Unmeasured illustration details are representative.
Salt crystal
A chosen 0.3 mm table-salt crystal. The irregular illustration is a scale specimen.
University of Utah — Cell size and scale

- Comparing
- Diameter ↔ Characteristic size
- Relative size
- Grain of sand is larger on this measurement by a factor of about 1.67. Grain of sand's selected measurement is approximately 66.7% greater than Salt crystal's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Grain of sand is labelled example; treat the displayed value as a comparison anchor rather than false precision.
- Salt crystal is labelled representative; treat the displayed value as a comparison anchor rather than false precision.
