Hi @mistletoe 

While you cannot directly change the font size, you can use the `await miro.board.createStickyNote` method to create a sticky note, and in there, you can use either the height or width parameter to increase the default size of the sticky. The font of the sticky will also increase to match the new size of the sticky. 

For example, you can try something like the code below which will set the height parameter to be larger than it normally is:

const stickyNote = await miro.board.createStickyNote({
  content: '<p>This is a sticky note. It looks just like the actual paper one.</p>',
  style: {
    fillColor: 'light_yellow', // Default value: light yellow
    textAlign: 'center', // Default alignment: center
    textAlignVertical: 'middle', // Default alignment: middle
  },
  x: 0, // Default value: horizontal center of the board
  y: 0, // Default value: vertical center of the board
  shape: 'square',
  height: 3300, // Set either 'width', or 'height'
});

// Output the created item to the developer console
console.log(stickyNote);

Hope it helps!
