The Size configuration of the Form affects the padding of all the editors and buttons.

    var fields = typeof(Telerik.Blazor.ThemeConstants.Form.Size)
        .GetFields(System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Static
        | System.Reflection.BindingFlags.FlattenHierarchy)
        .Where(field => field.IsLiteral && !field.IsInitOnly).ToList();

    foreach (var field in fields)
    {
        string size = field.GetValue(null).ToString();

        <div style="float:left; margin: 20px;">
            <TelerikForm Model="@TestUser"
                         Size="@size">
                <FormItems>
                    <FormItem Field="@nameof(User.FirstName)"></FormItem>
                    <FormItem Field="@nameof(User.LastName)"></FormItem>
                </FormItems>
            </TelerikForm>
        </div>
    }

    @code {

        public User TestUser { get; set; } = new User() {
            FirstName = "Johny",
            LastName = "Doe"
        };
