What are the canvas size dimensions that will match a standard 8.5x11 page?

Every time I export a looker studio report as a pdf to include in a written summary using word the page dimensions are off. Does anyone know the canvas size dimensions that will match US Standard 8.5x11?

Presumably any pixel settings with the correct ratios would work, but one that I tested and seemed to look good was Width: 1063 pixels and Height: 1375 pixels
