The CanvasRenderingContext2D.textAlign property of the Canvas 2D API specifies the current text alignment being used when drawing text. Beware that the alignment is based on the x value of the fillText() method. So if textAlign is "center", then the text would be drawn at x - (width / 2).

Syntax

ctx.textAlign = "left" || "right" || "center" || "start" || "end";

Options

Possible values:

left
The text is left-aligned.
right
The text is right-aligned.
center
The text is centered.
start
The text is aligned at the normal start of the line (left-aligned for left-to-right locales, right-aligned for right-to-left locales).
end
The text is aligned at the normal end of the line (right-aligned for left-to-right locales, left-aligned for right-to-left locales).

The default value is start.

Examples

Using the textAlign property

This is just a simple code snippet using the textAlign property to set a different text alignment.

HTML

<canvas id="canvas"></canvas>

JavaScript

var canvas = document.getElementById('canvas');
var ctx = canvas.getContext('2d');

ctx.font = '48px serif';
ctx.textAlign = 'left';
ctx.strokeText('Hello world', 0, 100);

Edit the code below and see your changes update live in the canvas:
