🔌Technology Tools
Technology tools for the device-and-display math that consumers and IT staff run into regularly: screen size and pixel density for choosing or comparing monitors and televisions, viewing-distance recommendations for a given resolution, aspect-ratio conversions for video work, and the small calculations around storage, bandwidth, and uptime. The category is heavier on consumer hardware than on enterprise infrastructure. The common misconception that costs people money is buying a screen by diagonal inches alone without checking pixel density; a 32-inch 4K display and a 32-inch 1080p display look very different at the same viewing distance, which is why the Screen Size Calculator reports PPI alongside the diagonal and the ideal viewing distance for the chosen resolution. If you are new to the category, start with the Screen Size Calculator before any monitor or television purchase, and pair it with the manufacturer's spec sheet rather than relying on retailer descriptions. The category will grow over time as we add tools for storage and bandwidth planning, which are the most commonly requested missing pieces. Send a request through the contact page if there is a calculation you keep running into.
