Keep the details in one place.
A screen diagonal does not tell you the width of an ultrawide monitor. Compare the ratio, physical dimensions and stand footprint.
Keep pixel resolution separate from screen dimensions. The calculator estimates visible image width and height from the diagonal and aspect ratio; the frame and stand need their own allowance.
Screen dimensions calculator
Convert a diagonal and aspect ratio into visible image width and height. Bezel, stand, throw distance and mounting clearance need separate checks.
