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);
The problem is Firefox doesn't listen to width and height. Disable that and your good to go.
input[type=checkbox] {_x000D_
width: 25px;_x000D_
height: 25px;_x000D_
-moz-appearance: none;_x000D_
}
_x000D_
<label><input type="checkbox"> Test</label>
_x000D_
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;
}

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 {

}
input[type=checkbox]:checked:after {
margin-left: 4px;
margin-top: -1px;

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 {

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!
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).
you can chnage the height and width in the code below
.checkmark {_x000D_
position: absolute;_x000D_
top: 0;_x000D_
left: 0;_x000D_
height: 20px;_x000D_
width: 20px;_x000D_
border-radius:5px;_x000D_
border:1px solid #ff7e02;_x000D_
}
_x000D_
<div class="check">_x000D_
_x000D_
<label class="container1">Architecture/Landscape_x000D_
_x000D_
_x000D_
<input type="checkbox" checked="checked">_x000D_
_x000D_
_x000D_
<span class="checkmark"></span>_x000D_
_x000D_
_x000D_
</label>_x000D_
</div>
_x000D_
An easy solution is use the property zoom
:
input[type="checkbox"] {_x000D_
zoom: 1.5;_x000D_
}
_x000D_
<input type="checkbox" />
_x000D_
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 */
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).
Scaling works on all browsers, but it will be blurry on Firefox and Safari.

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;
}

The other answers showed a pixelated checkbox, while I wanted something beautiful. The result looks like this:
Even though this version is more complicated I think it's worth giving it a try.

JSFiddle: https://jsfiddle.net/asbd4hpr/
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);
I just came out with this:
input[type="checkbox"] {display:none;}_x000D_
input[type="checkbox"] + label:before {content:"?";}_x000D_
input:checked + label:before {content:"?";}_x000D_
label:hover {color:blue;}
_x000D_
<input id="check" type="checkbox" /><label for="check">Checkbox</label>
_x000D_
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.
It's a little ugly (due to the scaling up), but it works on most newer browsers:
input[type=checkbox]_x000D_
{_x000D_
/* Double-sized Checkboxes */_x000D_

2017 version - using zoom or scale
Browser will use non-standard zoom
feature if it is supported (nice quality) or standard transform: scale
(blurry).
Scaling works on all browsers, but it will be blurry on Firefox and Safari.

Appearance:
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 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 */
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;
}
_x000D_
<label><input type="checkbox"> Test</label>
_x000D_
I just came out with this:
input[type="checkbox"] {display:none;}_x000D_
input[type="checkbox"] + label:before {content:"?";}_x000D_
input:checked + label:before {content:"?";}_x000D_
label:hover {color:blue;}
_x000D_
<input id="check" type="checkbox" /><label for="check">Checkbox</label>
_x000D_
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.
you can chnage the height and width in the code below
.checkmark {_x000D_
position: absolute;_x000D_
top: 0;_x000D_
left: 0;_x000D_
height: 20px;_x000D_
width: 20px;_x000D_
border-radius:5px;_x000D_
border:1px solid #ff7e02;_x000D_
}
_x000D_
<div class="check">_x000D_
_x000D_
<label class="container1">Architecture/Landscape_x000D_
_x000D_
_x000D_
<input type="checkbox" checked="checked">_x000D_

It's a little ugly (due to the scaling up), but it works on most newer browsers:
input[type=checkbox]_x000D_
{_x000D_
/* Double-sized Checkboxes */_x000D_
-ms-transform: scale(2); /* IE */_x000D_
-moz-transform: scale(2); /* FF */_x000D_
-webkit-transform: scale(2); /* Safari and Chrome */_x000D_
-o-transform: scale(2); /* Opera */_x000D_
transform: scale(2);_x000D_
padding: 10px;_x000D_
}_x000D_
_x000D_
/* Might want to wrap a span around your checkbox text */_x000D_
.checkboxtext_x000D_
{_x000D_
/* Checkbox text */_x000D_
font-size: 110%;_x000D_
display: inline;_x000D_
}
_x000D_
<input type="checkbox" name="optiona" id="opta" checked />_x000D_
<span class="checkboxtext">_x000D_
Option A_x000D_
</span>_x000D_
<input type="checkbox" name="optionb" id="optb" />_x000D_
<span class="checkboxtext">_x000D_
Option B_x000D_
</span>_x000D_
<input type="checkbox" name="optionc" id="optc" />_x000D_
<span class="checkboxtext">_x000D_

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!
