You can set the size of the Circular Gauge in pixel as demonstrated below.
@using Syncfusion.EJ2.Blazor.CircularGauge <EjsCircularGauge Width= "200px" Height= "200px"></EjsCircularGauge>
By setting value in percentage, gauge gets its dimension with respect to its container. For example, when the height is ‘50%’, gauge is rendered to half of the container height.
@using Syncfusion.EJ2.Blazor.CircularGauge <div style="height:450px; width:450px"> <EjsCircularGauge Width="50%" Height="50%"></EjsCircularGauge> </div>
Note: When you do not specify the size, it takes
450 pixels as the height and takes window size as its width.
