Is it possible to set the size of a checkbox using CSS or HTML across browsers?

width and size work in IE6+, but not with Firefox, where the checkbox stays 16x16 even if I set a smaller size.

    This is hard to do cross-browser. Roger Johansson has investigated this rather extensively. Commented Nov 20, 2008 at 21:45
  • Reading all the comments - there is a really simple way to do this without involving CSS: <input type="checkbox" name="checkboxName" value="on" style="width:110%; height:110%" > Commented Oct 23, 2018 at 15:45

It's a little ugly (due to the scaling up), but it works on most newer browsers:

input[type=checkbox]
{
  /* Double-sized Checkboxes */
  -ms-transform: scale(2); /* IE */
  -moz-transform: scale(2); /* FF */
  -webkit-transform: scale(2); /* Safari and Chrome */
  -o-transform: scale(2); /* Opera */
  transform: scale(2);
  padding: 10px;
}

/* Might want to wrap a span around your checkbox text */
.checkboxtext
{
  /* Checkbox text */
  font-size: 110%;
  display: inline;
}
<input  type="checkbox" name="optiona" id="opta" checked />
<span class="checkboxtext">
  Option A
</span>
<input type="checkbox" name="optionb" id="optb" />
<span class="checkboxtext">
  Option B
</span>
<input type="checkbox" name="optionc" id="optc" />
<span class="checkboxtext">
  Option C
</span>

this seems to be the correct answer as the one marked as answer offers no solutions in many cases (no solution to firefox on xp? no chrome at all?), is outdated and only contains a link and a comment of not much value.
@jdw +1 for this answer and even I had the need to do this and your answer was helpful. But somehow I find that the 'scaled' checkbox appears a little distorted. I don't know if this is a thing with FF or my OS (Ubuntu 12.04). Thanks anyway :)
the scale() needs 2 parameters for chrome, FF and IE I think. So if you just change all the scales to scale(2,2) it should work every browser.
add transform: scale(2); too, to ensure more for any browser
scaling looks aweful, at scale 2 you already see the individual pixels. I would never choose this solution for beautiful big css checkboxes.

Working solution for all modern browsers.

input[type=checkbox] {
    transform: scale(1.5);
}
<label><input type="checkbox"> Test</label>

Does this cover older browsers like ie 8?
@Huangism No, the code above won't have any effect in IE 8 which doesn't support the transform property. IE 9 supports -ms-transform which you could use, however some say it's quite pixelated so might be better to leave IE 9 with the default.
Isn't above approach bad, because there is a limit for scale as it causes checkbox to be pixelated.
Extremely pixelated on Chrome 64 with macOS 10.13.3 :( timo-ernst.net/misc/zeug/cb-pixel.jpg
Still pixelated on Chrome 76.

An easy solution is use the property zoom:

label {
  display: flex;
  align-items: center;
}

input[type="checkbox"] {
  zoom: 2;
}
<label>
  <input type="checkbox">
  <span>Agree</span>
</label>

Not sure it works in all browsers, but it looks prettier on screen than the scale transform solution.
On Chrome 64 with macOS 10.13.3 this looks way less pixelated than using transform + scale
Highly discouraged by Mozilla. developer.mozilla.org/en-US/docs/Web/CSS/zoom
It's kinda interesting that Mozilla is discouraging it while Firefox is almost the only browser that doesn't support it: caniuse.com/#feat=css-zoom
Update: Firefox supports it, Mozilla no longer discourages it.

2020 version - using pseudo-elements, size depends on font size.

Default checkbox/radio is rendered outside of screen, but CSS creates virtual elements very similar to default elements. Supports all browsers, no blur. Size depends on font size. Keyboard actions (space, tabs) are also supported.

2017 version - using zoom or scale

Browser will use non-standard zoom feature if it is supported (nice quality) or standard transform: scale (blurry on Safari) as fallback.

https://jsfiddle.net/ksvx2txb/11/

@supports (zoom:2) {
    input[type="radio"],  input[type=checkbox]{
    zoom: 2;
    }
}
@supports not (zoom:2) {
    input[type="radio"],  input[type=checkbox]{
        transform: scale(2);
        margin: 15px;
    }
}
label{
  /* fix vertical align issues */
    display: inline-block;
    vertical-align: top;
    margin-top: 10px;
}
<input type="radio" name="aa" value="1" id="aa" checked /> 
<label for="aa">Radio 1</label>
<br />
<input type="radio" name="aa" value="2" id="bb" /> 
<label for="bb">Radio 2</label>

Zoom looks like it works fine on FQ. Maybe watch out for older versions of Gecko?

I just came out with this:

input[type="checkbox"] {display:none;}
input[type="checkbox"] + label:before {content:"☐";}
input:checked + label:before {content:"☑";}
label:hover {color:blue;}
<input id="check" type="checkbox" /><label for="check">Checkbox</label>

Of course, thanks to this, you can change the value of content to your needs and use an image if you wish or use another font...

The main interest here is that:

  1. The checkbox size stays proportional to the text size

  2. You can control the aspect, the color, the size of the checkbox

  3. No extra HTML needed !

  4. Only 3 lines of CSS needed (the last one is just to give you ideas)

Edit: As pointed out in the comment, the checkbox won't be accessible by key navigation. You should probably add tabindex=0 as a property for your label to make it focusable.

Unfortunately, setting display:none on input will prevent it from being selected with tab key so I don't think this is a good idea.
Good remark. You could add tabindex=0 on the input to fix this.
I wonder if all those CSS rules may confuse some accessibility features?

@robertjd agreed, was confused about why this would be needed for a simple transform
@robertjd Those aren't even checkboxes; they're toggles.

The appearance of checkboxes seems to be fixed by default. But as pointed out by Worthy7 this can be remedied using CSS appearance property. It will make checkboxes completely empty, so you can define your own appearance. What is nice about this: You can use your existing HTML code. Downside: It is experimental technology. Edge (legacy) and IE do not use the custom style.

Here are the needed CSS styles:

input[type=checkbox] {
    width: 14mm;
    -webkit-appearance: none;
    -moz-appearance: none;
    height: 14mm;
    border: 0.1mm solid black;
}

input[type=checkbox]:checked {
    background-color: lightblue;
}

input[type=checkbox]:checked:after {
    margin-left: 4.3mm;
    margin-top: -0.4mm;
    width: 3mm;
    height: 10mm;
    border: solid white;
    border-width: 0 2mm 2mm 0;
    -webkit-transform: rotate(45deg);
    -moz-transform: rotate(45deg);
    -ms-transform: rotate(45deg);
    transform: rotate(45deg);
    content: "";
    display: inline-block;
}
<label><input type="checkbox"> Test</label>

I think the simplest solution is re-style the checkbox as some users suggest. The CSS below is working for me, only requires a few lines of CSS, and answers the OP question:

input[type=checkbox] {
    -webkit-appearance: none;
    -moz-appearance: none;
    vertical-align: middle;
    width: 14px; 
    height: 14px;
    font-size: 14px;
    background-color: #eee;
}

input[type=checkbox]:checked:after {
    position: relative;
    bottom: 3px;
    left: 1px;
    color: blue;
    content: "\2713"; /* check mark */
}

As mentioned in this post, the zoom property seems not to work on Firefox, and transforms may cause undesired effects.

Tested on Chrome and Firefox, should work for all modern browsers. Just change the properties (colors, size, bottom, left, etc.) to your needs. Hope it helps!

I was looking to make a checkbox that was just a little bit larger and looked at the source code for 37Signals Basecamp to find the following solution-

You can change the font size to make the checkbox slightly larger:

font-size: x-large;

Then, you can align the checkbox properly by doing:

vertical-align: top;
margin-top: 3px; /* change to center it */

font-size doesn't seem to affect the size of the actual checkbox at all

You can make checkboxes larger in Safari — which is generally resistant to the usual approaches — with this attribute: -webkit-transform: scale(1.3, 1.3);

My reputation is slightly too low to post comments, but I made a modification to Jack Miller's code above in order to get it to not change size when you check and uncheck it. This was causing text alignment problems for me.

    input[type=checkbox] {
        width: 17px;
        -webkit-appearance: none;
        -moz-appearance: none;
        height: 17px;
        border: 1px solid black;
    }

    input[type=checkbox]:checked {
        background-color: #F58027;
    }

    input[type=checkbox]:checked:after {
        margin-left: 4px;
        margin-top: -1px;
        width: 4px;
        height: 12px;
        border: solid white;
        border-width: 0 2px 2px 0;
        -webkit-transform: rotate(45deg);
        -moz-transform: rotate(45deg);
        -ms-transform: rotate(45deg);
        transform: rotate(45deg);
        content: "";
        display: inline-block;
    }
    input[type=checkbox]:after {

use this css code

{
  /* Double-sized Checkboxes */
  -ms-transform: scale(1.5); /* IE */
  -moz-transform: scale(1.5); /* FF */
  -webkit-transform: scale(1.5); /* Safari and Chrome */
  -o-transform: scale(1.5); /* Opera */
  transform: scale(1.5);

My understanding is that this isn't easy at all to do cross-browser. Instead of trying to manipulate the checkbox control, you could always build your own implementation using images, javascript, and hidden input fields. I'm assuming this is similar to what niceforms is (from Staicu lonut's answer above), but wouldn't be particularly difficult to implement. I believe jQuery has a plugin to allow for this custom behavior as well (will look for the link and post here if I can find it).

I found this CSS-only library to be very helpful: https://lokesh-coder.github.io/pretty-checkbox/

Or, you could roll your own with this same basic concept, similar to what @Sharcoux posted. It's basically:

  • Hide the normal checkbox (opacity 0 and placed where it would go)
  • Add a css-based fake checkbox
  • Use input:checked~div label for the checked style
  • make sure your <label> is clickable using for=yourinputID

.pretty {
  position: relative;
  margin: 1em;
}
.pretty input {
  position: absolute;
  left: 0;

The problem is Firefox doesn't listen to width and height. Disable that and your good to go.

input[type=checkbox] {
    width: 25px;
    height: 25px;
    -moz-appearance: none;
}
<label><input type="checkbox"> Test</label>

This simply makes the entire checkbox disappear. You then have to provide a background color to see it. But then how do you make the check mark appear? This answer is incomplete.

The other answers showed a pixelated checkbox, while I wanted something beautiful. The result looks like this: checkbox preview

Even though this version is more complicated I think it's worth giving it a try.

.checkbox-list__item {
  position: relative;
  padding: 10px 0;
  display: block;
  cursor: pointer;
  margin: 0 0 0 34px;
  border-bottom: 1px solid #b4bcc2;
}
.checkbox-list__item:last-of-type {
  border-bottom: 0;
}

.checkbox-list__check {
  width: 18px;
  height: 18px;
  border: 3px solid #b4bcc2;
  position: absolute;
  left: -34px;
  top: 50%;
  margin-top: -12px;
  transition: border .3s ease;
  border-radius: 5px;
}
.checkbox-list__check:before {
  position: absolute;
  display: block;
  width: 18px;
  height: 22px;
  top: -2px;
  left: 0px;
  padding-left: 2px;
  background-color: transparent;
  transition: background-color .3s ease;
  content: '\2713';
  font-family: initial;
  font-size: 19px;
  color: white;
}

input[type="checkbox"]:checked ~ .checkbox-list__check {
  border-color: #5bc0de;
}
input[type="checkbox"]:checked ~ .checkbox-list__check:before {
  background-color: #5bc0de;
}
<label class="checkbox-list__item">
  <input class="checkbox_buttons" type="checkbox" checked="checked" style="display: none;">
  <div class="checkbox-list__check"></div>
</label>

Put the checkbox inside a parent with display:grid and make sure it doesn't have margin:auto

https://codepen.io/sneffel/pen/oNPYvBx

 body{
     text-align:center;
}
 .grid{
    display:grid;
}
 input{
    height:25px;
}
<div class="container grid">
  <input type="checkbox" id="first">
</div>
<form class="container">
  <input type="checkbox" id="second">
</form>

You can change the height and width in the code below

.checkmark {
    position: absolute;
    top: 0;
    left: 0;
    height: 20px;
    width: 20px;
    border-radius:5px;
    border:1px solid #ff7e02;
}
<div class="check">

     <label class="container1">Architecture/Landscape
                                          

    <input type="checkbox" checked="checked">
                                          

    <span class="checkmark"></span>
                                 

    </label>
</div>

None of the above worked with my iPhone 7 and Safari browser. I had to add the style settings into the html code not in the style sheet (style.css or alike):

<input type="checkbox" style="min-height:30px;min-width:30px;">
