If the canvas looks distorted, then try to change the height and width −
<canvas id = ”canvas1” width = '400' height = '300'></canvas>
The default height and width of the canvas in HTML5 is of 2/1 ratio −
width = 300 height = 150
Example
Let us see an example −
<!DOCTYPE HTML>
<html>
<head>
<style>
#mycanvas{border:1px solid red;}
</style>
</head>
<body>
<canvas id = "mycanvas" width = "100" height = "100"></canvas>
</body>
</html>Output
