Triangle Centroid Calculator

Triangle Centroid Calculator for layout notes, drafting, and classroom geometry when you want a fixed formula answer without improvising the math by hand.

Enter job values, review the estimate, then use the decision hints before ordering or quoting.

Estimate Results

Enter values to see the result.

Formula

centroid = ((x1+x2+x3)/3, (y1+y2+y3)/3)

Average the three x-coordinates and the three y-coordinates separately.

The centroid is the balance point of the triangle.

Example

1, 1, 7, 1, 4, 7 gives Centroid X 4, Centroid Y 3.

Check

Mixing units, scales, or coordinate conventions across x1, y1, x2, y2, x3, y3 before calculating centroid x and centroid y.
Rounding too early when the result still feeds another geometry or algebra step.
