Card Width and Height – Android Jetpack Compose

Set Width and Height of Card composable in Android Jetpack Compose

In this tutorial, we shall learn how to set a specific width and height for a Card composable in Android Jetpack Compose, using modifier property.

The following is an example for a Card with a height of 150.dp and a width of 200.dp.

The sample code snippet to set width and height for a Card composable is given below.

Card(
    modifier = Modifier
        .size(width = 300.dp, height = 200.dp)
) 

Now, we shall take an example Android application, that displays a Card composable with a specific width of 300.dp and a height of 200.dp. You can change these dimensions to suit your requirements.

            Text(
                text = "This is some sample text inside the card. You can add more content here.",
                color = MaterialTheme.colorScheme.onSurface
            )
