My SKTexture is size wrong for my SKSpriteNode

Question

I have a 200 x 100 box-like menu button SKSpriteNode declared below.

menuBtn.size = CGSize(width: scrWidth * 1.5, height: 100)
menuBtn.texture = SKTexture(image: UIImage(named: "menuBtn")!)

The problem is, the hitbox for the button is still right, and the width of the SKTexture is fine, but the height of the SKTexture is around 1/2 the size of the actual menuBtn. It is a png, and I've checked and there's no clear textures around the sprite (just the transparent png ones), what am I doing wrong?

The texture's png image size is 1044x1044 if that has any impact.

First of all, make sure you are sending the correct size to your scene from GameViewController to your scene, in this example GameScene.

// without .sks

class GameViewController: UIViewController 
{
    override func viewDidLoad() 
    {
        super.viewDidLoad()

        // ...        

        if let view = self.view as! SKView?
        {
            let scene = GameScene()

            // Set the scale mode to scale to fit the window
            scene.scaleMode = .aspectFit

            // Set anchorPoint and pass scene.size
            scene.anchorPoint = CGPoint(x: 0.5, y: 0.5)
            scene.size = view.bounds.size

            // Present the scene
            view.presentScene(scene)
        }

        // ...
}

// with .sks

class GameViewController: UIViewController 
{
    override func viewDidLoad() 
    {
        super.viewDidLoad()

        // ...   

        if let view = self.view as! SKView? 
        {
            if let scene = SKScene(fileNamed: "GameScene.sks") 
            {
                // Set the scale mode to scale to fit the window
                scene.scaleMode = .aspectFit

                // Pass scene.size
                scene.size = view.bounds.size

                // Present the scene
                view.presentScene(scene)
            } 
        }

        // ...
}

In your GameScene create the object. I recommend working in screenWidth and screenHeight when you create objects so they scale to all iOS devices.

class GameScene: SKScene 
{
    override func didMove(to view: SKView) 
    {
        // ...

        // scene width / height
        let sceneWidth = size.width
        let sceneHeight = size.height

        // object
        let menu : SKSpriteNode = SKSpriteNode()
        menu.texture = SKTexture(imageNamed: "menu")
        menu.size = CGSize(width: sceneWidth * 0.75, height: 100)
        let y_pos : CGFloat = -sceneHeight * 0.5 + menu.size.height * 0.5
        menu.position = CGPoint(x: 0, y: y_pos)
        menu.zPosition = 1
        addChild(menu)

        // ...
   }
}
