https://github.com/alexeyten/qr-image#options There is size option which set width and height of one square of image.

var qr = require('qr-image');

var qr_png = qr.image('I love QR!', { type: 'png', size: 10 });
qr_png.pipe(require('fs').createWriteStream('i_love_qr.png'));

You can't directly set size of result image because it's depend on length of text and error correction level.
