How to estimate story points in Agile

Story points are most useful when teams follow one shared estimation model. This guide gives a practical approach you can apply immediately.

Start with reference stories

Define 2-3 baseline stories and compare new work against them to keep point sizing stable.

Vote independently

Private voting before reveal reduces authority bias and improves estimate quality.

Discuss disagreements only

Focus discussion on outliers and assumptions that caused the difference.

Calibrate continuously

Review outcomes after each sprint and tune your estimation scale gradually.
