My case was to print horizontal (landscape) summary section - so:

}).then((canvas) => {
  const img = canvas.toDataURL('image/jpg');
  new jsPDF({
        orientation: 'l', // landscape
        unit: 'pt', // points, pixels won't work properly
        format: [canvas.width, canvas.height] // set needed dimensions for any element
  });
  pdf.addImage(img, 'JPEG', 0, 0, canvas.width, canvas.height);
  pdf.save('your-filename.pdf');
});

For anyone trying to this in react. There is a slight difference.

// Document of 8.5 inch width and 11 inch high
new jsPDF('p', 'in', [612, 792]);

or 

// Document of 8.5 inch width and 11 inch high
new jsPDF({
        orientation: 'p', 
        unit: 'in', 
        format: [612, 792]
});

When i tried the @Aidiakapi solution the pages were tiny. For a difference size take size in inches * 72 to get the dimensions you need. For example, i wanted 8.5 so 8.5 * 72 = 612. This is for [email protected].

Besides using one of the default formats you can specify any size you want in the unit you specify.

For example:

// Document of 210mm wide and 297mm high
new jsPDF('p', 'mm', [297, 210]);
// Document of 297mm wide and 210mm high
new jsPDF('l', 'mm', [297, 210]);
// Document of 5 inch width and 3 inch high
new jsPDF('l', 'in', [3, 5]);

The 3rd parameter of the constructor can take an array of the dimensions. However they do not correspond to width and height, instead they are long side and short side (or flipped around).

Your 1st parameter (landscape or portrait) determines what becomes the width and the height.

In the sourcecode on GitHub you can see the supported units (relative proportions to pt), and you can also see the default page formats (with their sizes in pt).
