Frequently Asked Questions
Find immediate answers to common questions about device updates, formulas, citation guidelines, and our site policies.
How do I request a new device preset or screen size?
We welcome suggestions for newly released laptops, ultrawide monitors, TVs, and mobile displays. Simply select "Request New Device Preset" in the form above and provide the device make, model, diagonal screen size, native resolution, and aspect ratio. We verify display specs against manufacturer data sheets before publishing.
What mathematical standards do your calculators follow?
Our calculators use standard trigonometric and optical formulas. Viewing distances are based on SMPTE (30° visual field of view) and THX (36° to 40° field of view) cinematic guidelines. PPI calculations follow the Euclidean distance formula divided by the physical diagonal. You can find detailed mathematical formulas on our individual calculator pages.
