+## Description
+
+How do I stretch the Switch horizontally, in order to see the whole dynamic on/off text labels? The goal is to expand the component and fit the complete text automatically inside the TelerikSwitch dynamically at runtime. Setting the width to a fixed value is not a viable solution.
+
+## Solution
+
+The Switch relies on absolute positioning styles, which require defined dimensions to work properly. However, it is possible to calculate the Switch width dynamically, based on the length of its labels.

+````CSHTML
+<TelerikSwitch Value="@Value"
+               Width="@Width"
+               OnLabel="@OnLabel"
+               OffLabel="@OffLabel"></TelerikSwitch>
+
+@code {
+    bool Value { get; set; }
+    string OnLabel { get; set; } = "Long text on";
+    string OffLabel { get; set; } = "Long text off and some more text";
+
+    string Width
+    {
+        get
+        {
+            return Math.Max(OnLabel.Length, OffLabel.Length) * .8 + "em";
+        }
+    }
+}
