How to adjust size of TextSprite?

[RylanSchaeffer]

I have a fixed scene with a stationary camera. When I try creating the TextSprite, the text is massive and I have to push it back along the z axis significantly to get it to fit. What's the right way to resize the sprite?

        practiceErrorSprite = new THREE.TextSprite({
            text: 'Not Quite! Try again',
            alignment: 'center',
            // fontFamily: 'Arial, Helvetica, sans-serif',
            fontSize: 8,
            fontStyle: 'bold',
            color: '#ec1b27',
        });
        practiceErrorSprite.visible = false;
        // practiceErrorSprite.scale.set(0.1, 0.1, 0.1)
        // Can't figure out how to resize.
        practiceErrorSprite.position.set(0, -40, -70)
        scene.add(practiceErrorSprite);

FontSize is the real size of the letters in space. Try to set fontSize to 0.1.

When I try setting fontSize to less than 1, the sprite disappears :(

fontSize is 1 here:

fontSize is 0.5 here:

Actually, the phenomenon is more inconsistent. Here is fontSize at 0.9:

0.6

0.4 disappears

0.5 disappears

0.55 works

0.5 again, confirming that the text does indeed disappear
