Text is too small while displaying in device

I customized for About screen. I wrote code for displaying text in screen. But when i run the app in device the texts are too small. See the attached image

using UnityEngine;

using System.Collections;


public class Aboutscreen : MonoBehaviour {





// public GUIStyle emptyButtonStyle;


// Use this for initialization

void Start () {




// Update is called once per frame

void Update () {





void OnGUI()


GUI.Label(new Rect(10f, 160f, Screen.width, 250f), "1.Print the alphabet image targets located at");


GUI.Label(new Rect(10f, 300f, 400f, 300f), "2.Point any of the animal images");


GUI.Label(new Rect(10f, 460f, 400f, 400f), "3.Finally your kids able to see the 3D animal render on the screen with soundss");


if(GUI.Button(new Rect(80,680,280,200), "start")) {




       GUI.backgroundColor = Color.clear;


       if(GUI.Button(new Rect(260,160,120,250), "www.url.net")) {






You can either use a custom GUI skin, which is probably the best method. Or you can change the text font size at run time.

GUI.skin.label.fontSize = 50;     //changes font size to 50 for labels
GUI.skin.button.fontSize = 50;     //changes font size to 50 for buttons
