Looked through the code and nothing jumped out at me.

Thanks

@moneyhan Just specify a larger cellSize and/or margin parameter when calling one of the create methods, for example:

var typeNumber = 4,
    errorCorrectionLevel = 'L',
    cellSize = 5,
    margin = 10;
var qr = qrcode(typeNumber, errorCorrectionLevel);
qr.addData('Hi!');
qr.make();
document.getElementById('placeHolder').innerHTML = qr.createImgTag(cellSize, margin);
