Custom Renderer is needed for this scenario. Create a class CustomDataFormRenderer which inherits from DataFormRenderer. Then override the UpdateEditor method and use the SetTextSize method to change the Font Size of the EditorView text:

using Android.Content;
using Android.Runtime;
using AndroidX.AppCompat.Widget;
using App1.Droid;
using Com.Telerik.Widget.Dataform.Visualization.Core;
using Com.Telerik.Widget.Dataform.Visualization.Editors;
using Telerik.XamarinForms.InputRenderer.Android;
using Xamarin.Forms;

[assembly: ExportRenderer(typeof(Telerik.XamarinForms.Input.RadDataForm), typeof(CustomDataFormRenderer))]

namespace App1.Droid
    public class CustomDataFormRenderer : DataFormRenderer
        public CustomDataFormRenderer(Context context) : base(context)

        protected override void UpdateEditor(EntityPropertyEditor editor, Telerik.XamarinForms.Input.DataForm.IEntityProperty property)
            base.UpdateEditor(editor, property);

            if (editor is DataFormTextEditor || editor is DataFormDecimalEditor || editor is DataFormIntegerEditor)
                var editText = editor.EditorView.JavaCast<AppCompatEditText>();
                editText.SetTextSize(Android.Util.ComplexUnitType.Px, 80);
