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.
style=
tag is CSS...
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; } Option A Option B Option C
Working solution for all modern browsers.
input[type=checkbox] { transform: scale(1.5); }
IE: 10+
FF: 16+
Chrome: 36+
Safari: 9+
Opera: 23+
iOS Safari: 9.2+
Chrome for Android: 51+
Appearance:
Chrome 58 (May 2017), Windows 10
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.
An easy solution is use the property zoom
:
input[type="checkbox"] { zoom: 1.5; }
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;
}
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;}
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:
The checkbox size stays proportional to the text size You can control the aspect, the color, the size of the checkbox No extra HTML needed ! 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.
display:none
on input will prevent it from being selected with tab
key so I don't think this is a good idea.

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; }

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 */
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);
This should work
input {
width: 25px;
height: 25px;
}
It worked for me for Firefox and Chrome and iPhone's Firefox, Chrome and Safari at least.
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
.pretty { position: relative; margin: 1em; } .pretty input { position: absolute; left: 0; top: 0; min-width: 1em; width: 100%; height: 100%; z-index: 2; opacity: 0; margin: 0; padding: 0; cursor: pointer; } .pretty-inner { box-sizing: border-box; position: relative; } .pretty-inner label { position: initial; display: inline-block; font-weight: 400; margin: 0; text-indent: 1.5em; min-width: calc(1em + 2px); } .pretty-inner label:after, .pretty-inner label:before { content: ''; width: calc(1em + 2px); height: calc(1em + 2px); display: block; box-sizing: border-box; border-radius: 0; border: 1px solid transparent; z-index: 0; position: absolute; left: 0; top: 0; background-color: transparent; } .pretty-inner label:before { border-color: #bdc3c7; } .pretty input:checked~.pretty-inner label:after { background-color: #00bb82; width: calc(1em - 6px); height: calc(1em - 6px); top: 4px; left: 4px; } /* Add checkmark character style */ .pretty input:checked~.pretty-inner.checkmark:after { content: '\2713'; color: #fff; position: absolute; font-size: 0.65em; left: 6px; top: 3px; } body { font-size: 20px; font-family: sans-serif; }
use this css code
input[type=checkbox]
{
/* 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);
padding: 10px;
}
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; }

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; }

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 { margin-left: 4px; margin-top: -1px; width: 4px; height: 12px; border: solid white; border-width: 0; -webkit-transform: rotate(45deg); -moz-transform: rotate(45deg); -ms-transform: rotate(45deg); transform: rotate(45deg); content: ""; display: inline-block; }
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; }
Success story sharing
transform: scale(2);
