Comparatives of proportion (har qadr... be hamân nesbat)

Proportional Comparisons

When discussing economics, demographics, or shifting trends, you often need to show how two factors move in tandem—like saying "the more supply decreases, the more prices rise."

In formal Farsi, we express this proportional relationship using a correlative structure: هر قدر (however much / the more) introduces the first clause, and به همان نسبت (by the same proportion) introduces the second.

Notice how both halves of the comparison are standard, complete clauses using verbs in the Indicative tense.

To the Same Extent

For variety, you can easily swap out به همان نسبت for به همان اندازه (to the same extent). The grammatical structure remains exactly the same, cleanly linking two shifting realities together.

Building Complex Sentences

Because this correlative structure simply links two standard clauses, you can seamlessly embed the entire "the more... the more..." package inside a larger sentence as a subordinate thought.

You might also notice that the subject of the first clause can appear before هر قدر rather than after it. This shifts the focus slightly onto the subject doing the action, without altering the grammar of the proportion.
