Gene Coordinate Length
Calculate gene length from one-based inclusive start and end coordinates: end − start + 1. Inclusive coordinates count both endpoint bases, so a feature whose start and end are equal is one base pair long.
Description
Calculate gene length from one-based inclusive start and end coordinates: end − start + 1. Inclusive coordinates count both endpoint bases, so a feature whose start and end are equal is one base pair long.
Gene Coordinate Length is a focused biology tool that calculate gene length from one-based inclusive start and end coordinates: end − start + 1. Inclusive coordinates count both endpoint bases, so a feature whose start and end are equal is one base pair long. It calculates locally from the values you enter and exposes the result without changing the source observations.1
When to use Gene Coordinate Length
Use Gene Coordinate Length when you need to calculate gene length from one-based inclusive start and end coordinates: end − start + 1. Inclusive coordinates count both endpoint bases, so a feature whose start and end are equal is one base pair long. Enter Start position and End position using the definitions and units below so the result can be reproduced.
- Start position
- An integer count or setting greater than or equal to 1, expressed in bp.
- End position
- An integer count or setting greater than or equal to 1, expressed in bp.
How Gene Coordinate Length calculates the result
The published tool contract uses this rule: Calculate gene length from one-based inclusive start and end coordinates: end − start + 1. Inclusive coordinates count both endpoint bases, so a feature whose start and end are equal is one base pair long.

- The calculated gene length in bp.
Limitations of Gene Coordinate Length
The calculation does not propagate measurement uncertainty, sampling error, or biological and chemical variability.
Alternative or Complementary measurements
Retain the original Start position and End position values and their units alongside the result. Sequence Length is useful when you instead need to count the number of characters in a nucleotide sequence. Transcript Length nt provides another view by helping you report the length of a transcript in nucleotides.
