If you need to calculate the cost depending on measurements (for example, doors), then how can this be considered?

Question

WordPress

If this is not a static variation with a price, but so that users can enter their measurements, and it counts.
What do you personally use for this?
Please share a link to a snippet (it would be ideal, I'll sort it out) or a plugin.

Answer 1

Make a simple JS calculator.

Answer 2

No snippet. People sit down and calculate 90% of cases. You put all this into the calculator.
