p5.js square() Function Last Updated : 12 Jul, 2025 Comments Improve Suggest changes Like Article Like Report The square() function is an inbuilt function in p5.js which is used to draw the square on the screen. A square contains four equal sides and four angles each of 90 degrees. It is the special case of a rectangle where width and height are equal. Syntax: square( x, y, s, tl, tr, br, bl ) Parameters: This function accept many parameters as mentioned above and described below: x: It is used to set the x-coordinate of square. y: It is used to set the y-coordinate of square. s: It is used to set the size of side of square. tl: It is optional parameter and used to set the radius of top-left corner. tr: It is optional parameter and used to set the radius of top-right corner. br: It is optional parameter and used to set the radius of bottom-right corner. bl: It is optional parameter and used to set the radius of bottom-left corner. Example 1: javascript function setup() { // Create Canvas of given size createCanvas(300, 300); } function draw() { background(220); // Use color() function let c = color('green'); // Use fill() function to fill color fill(c); // Draw a square square(50, 50, 200); } Output: Example 2: javascript function setup() { // Create Canvas of given size createCanvas(300, 300); } function draw() { background(220); // Use color() function let c = color('green'); // Use fill() function to fill color fill(c); // Draw a square square(50, 50, 200, 20); } Output: Example 3: javascript function setup() { // Create Canvas of given size createCanvas(300, 300); } function draw() { background(220); // Use color() function let c = color('green'); // Use fill() function to fill color fill(c); // Draw a square square(50, 50, 200, 10, 20, 30, 40); } Output: Online editor: https://editor.p5js.org/ Environment Setup: https://www.geeksforgeeks.org/javascript/p5-js-soundfile-object-installation-and-methods/ Reference: https://p5js.org/reference/#/p5/square Comment More infoAdvertise with us Next Article Introduction to JavaScript J jit_t Follow Improve Article Tags : JavaScript Web Technologies JavaScript-p5.js Similar Reads JavaScript Tutorial JavaScript is a programming language used to create dynamic content for websites.
