How To Set Checkbox Size in HTML/CSS?

Last Updated : 11 Jan, 2025

Resizing checkboxes in HTML/CSS can be achieved using several methods. Here are the most effective techniques:

1. Using width and height Properties

By setting the width and height properties, you can directly define the dimensions of the checkbox.

html

<html>
<head>
    <style>
        input[type="checkbox"] {
            width: 20px;
            height: 20px;
        }
    </style>
</head>
<body>
    <label>
        <input type="checkbox" name="option1">
        Option 1
    </label>
    <label>
        <input type="checkbox" name="option2">
        Option 2
    </label>
</body>
</html>

In this Example:

The input[type="checkbox"] selector targets all checkbox inputs.
Setting width: 20px; and height: 20px; increases the checkbox size to 20x20 pixels.

2. Using the transform Property

The transform: scale() property scales the checkbox without altering its proportions.

html

<html>
<head>
    <style>
        input[type="checkbox"] {
            transform: scale(1.5);
            margin: 10px;
        }
    </style>
</head>
<body>
    <label>
        <input type="checkbox" name="option1">
        Option 1
    </label>
    <label>
        <input type="checkbox" name="option2">
        Option 2
    </label>
</body>
</html>

In this Example:

The transform: scale(1.5); property enlarges the checkbox by 1.5 times its original size.
Adding margin: 10px; ensures adequate spacing around the checkbox.

3. Using the zoom Property

The zoom property can also adjust the size of the checkbox.

HTML

<html>
<head>
    <style>
        input[type="checkbox"] {
            zoom: 1.5;
            margin: 10px;
        }
    </style>
</head>
<body>
    <label>
        <input type="checkbox" name="option1">
        Option 1
    </label>
    <label>
        <input type="checkbox" name="option2">
        Option 2
    </label>
</body>
</html>

In this Example:

The zoom: 1.5; property increases the checkbox size by 1.5 times.
Note that the zoom property is non-standard and may not work consistently across all browsers.
