Change SVG Size In Angular Material 2 Using Vanilla CSS Or HTML

Answer :

It seems that library styles override your css inline declaration. Try maybe to add !important declaration to your style: style="font-size: 16 !important" or since you didn't provide more code, try to inspect this icon node, to check which style define the font-size.

UPDATE:

Here is another possibly working solution. Add transform: scale(2); style for svg element you want to resize, where 2 is 200% of actual size (of course you can also downsize them using for example 0.5 value for 50%). Here is working sample for the website with your icons and link to documnetation:

.size-24 button svg {     width: 24px;     height: 24px;     transform: scale(2); } 

I played with this for way too long.

I have a series of icons that I want to be scaled to fit in various mat-icon sizes, but each icon needs a different scale so they appear balanced with the other icons - effectively increasing the size of the viewBox.

In the end this worked well enough:

mat-icon {     width: 50px;     height: 50px;      display: flex;     flex-shrink: 0;     justify-content: center;      outline: 1px dashed red;  // for testing          & ::ng-deep svg     {         align-self: center;     }      &.shrink-90 ::ng-deep svg     {         width: 90%;         height: 90%;     }      &.shrink-80 ::ng-deep svg     {         width: 80%;         height: 80%;     } } 

Then I create the mat-icon with this, where iconCss='shrink-80'

   <mat-icon svgIcon="{{ feature.name }}" [ngClass]="feature.iconCss"></mat-icon> 

The mat-icon itself can be scaled with whatever additional classes you want (just like you would for a normal icon). Then the 'shrinking' adjusts the size within the box.

Taking @mpro solution, I did some changes that work better for me ( I have custom icons so maybe that's the reason why):

mat-icon[size="2"]{   width: 48px;   height: 48px; }  mat-icon[size="2"] svg{   transform: scale(2);   transform-origin: left top; } 

or the scss solution:

@mixin iconSize($size){   &[size="#{$size}"]{     width: 24px*$size;     height: 24px*$size;      svg{       transform: scale($size);       transform-origin: left top;     }   } }
