Increase Size of SVG Animation - html

Question

I'm using this CSS checkmark animation I found for a success page. It works well, but a bit small. I'd like to increase it in size to about 300 pixels.
I tried increasing the viewBox size to 300, but it didn't work:
<svg class="checkmark" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 300 300">
<circle class="checkmark__circle" cx="26" cy="26" r="25" fill="none"/>
<path class="checkmark__check" fill="none" d="M14.1 27.2l7.1 7.2 16.7-16.8"/>
</svg>
What is the correct way to increase the size?
.checkmark__circle {
stroke-dasharray: 166;
stroke-dashoffset: 166;
stroke-width: 2;
stroke-miterlimit: 10;
stroke: #7ac142;
fill: none;
animation: stroke 0.6s cubic-bezier(0.65, 0, 0.45, 1) forwards;
}
.checkmark {
width: 56px;
height: 56px;
border-radius: 50%;
display: block;
stroke-width: 2;
stroke: #fff;
stroke-miterlimit: 10;
margin: 10% auto;
box-shadow: inset 0px 0px 0px #7ac142;
animation: fill .4s ease-in-out .4s forwards, scale .3s ease-in-out .9s both;
}
.checkmark__check {
transform-origin: 50% 50%;
stroke-dasharray: 48;
stroke-dashoffset: 48;
animation: stroke 0.3s cubic-bezier(0.65, 0, 0.45, 1) 0.8s forwards;
}
#keyframes stroke {
100% {
stroke-dashoffset: 0;
}
}
#keyframes scale {
0%, 100% {
transform: none;
}
50% {
transform: scale3d(1.1, 1.1, 1);
}
}
#keyframes fill {
100% {
box-shadow: inset 0px 0px 0px 30px #7ac142;
}
}
<svg class="checkmark" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 52 52">
<circle class="checkmark__circle" cx="26" cy="26" r="25" fill="none"/>
<path class="checkmark__check" fill="none" d="M14.1 27.2l7.1 7.2 16.7-16.8"/>

I've left three comments below indicating the sizes you need to increase, all in CSS:
The SVG width
The SVG height
The shadow "fill" in the animation (set to 50% the size of the width/height)
.checkmark__circle {
stroke-dasharray: 166;
stroke-dashoffset: 166;
stroke-width: 2;
stroke-miterlimit: 10;
stroke: #7ac142;
fill: none;
animation: stroke 0.6s cubic-bezier(0.65, 0, 0.45, 1) forwards;
}
.checkmark {
width: 200px; /* 1. change the width here */
height: 200px; /* 2. change the height here */
border-radius: 50%;
display: block;
stroke-width: 2;
stroke: #fff;
stroke-miterlimit: 10;
margin: 10% auto;
box-shadow: inset 0px 0px 0px #7ac142;
animation: fill .4s ease-in-out .4s forwards, scale .3s ease-in-out .9s both;
}
.checkmark__check {
transform-origin: 50% 50%;
stroke-dasharray: 48;
stroke-dashoffset: 48;
animation: stroke 0.3s cubic-bezier(0.65, 0, 0.45, 1) 0.8s forwards;
}
#keyframes stroke {
100% {
stroke-dashoffset: 0;
}
}
#keyframes scale {
0%,
100% {
transform: none;
}
50% {
transform: scale3d(1.1, 1.1, 1);
}
}
#keyframes fill {
100% {
/* 3. change the shadow spread-radius here to 50% the width/height */
box-shadow: inset 0px 0px 0px 100px #7ac142;
}
}
<svg class="checkmark" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 52 52">
<circle class="checkmark__circle" cx="26" cy="26" r="25" fill="none"/>
<path class="checkmark__check" fill="none" d="M14.1 27.2l7.1 7.2 16.7-16.8"/>
