why canvas width is double in html then adobe animate document width

[Shabbar28866904fotm]

Adobe animate document width is 900 while canvas width is double 1800 in HTML, why is this  

[Shabbar28866904fotm]

it looks like it is due to Window: devicePixelRatio property

so, your question is answered?

Yes to some extent, I calculate canvas width and height by multiplying with devicePixelRatio

var pRatio = window.devicePixelRatio || 1;


function handleMouseMove(evt) {
    if (oldX) {
        drawingCanvas.graphics.beginStroke(color)
            .setStrokeStyle(size, "round")
            .moveTo(oldX, oldY)
            .lineTo(evt.stageX / pRatio, evt.stageY / pRatio);
        stage.update();
    }
    oldX = evt.stageX / pRatio;
    oldY = evt.stageY / pRatio;

}
