Preschool Reading Level Calculator — How It Works

Estimates an appropriate reading level (Lexile range) for a given school grade.

How it works

  1. Enter a school grade level.
  2. The tool estimates a typical Lexile reading range for that grade.

Formula

Estimated Lexile range ≈ (Grade × 100 − 50)L to (Grade × 100 + 100)L

Example

For grade 4, the estimated range is about 350L–500L.

Notes

Lexile ranges vary significantly between individual readers, curricula, and regions. This gives a general starting point — a formal reading assessment provides a more precise measure for an individual student.
