Screen Compare Before Buying: The Complete Checklist for Phones, TVs & Monitors

Buying a new phone, TV, or monitor without doing a proper screen compare is one of the most common — and most expensive — mistakes tech buyers make. You read the specs, see a diagonal measurement, and assume you know what you're getting. But screen size numbers are misleading without context. A 6.7-inch phone and a 6.9-inch phone sound almost identical, yet the larger one has 6% more screen area and a noticeably bigger body. A 55-inch TV vs a 65-inch TV sounds like a modest upgrade, but you're getting 40% more screen. This checklist will walk you through every factor to compare before you click "buy."

Before we dive in — bookmark the Easy Compare screen comparison tool. It lets you compare any two screen sizes side by side at true scale, and you'll want it handy as you work through this checklist.

Screen Compare Checklist: The 8 Things That Actually Matter

✅ 1. Screen Area, Not Just Diagonal

The diagonal measurement is a legacy spec from the CRT era. What actually determines how much content you see is screen area (width × height). When you compare screens, always check the area difference. For example:

✅ 2. Resolution and Pixel Density (PPI)

A bigger screen at the same resolution means lower pixel density, which means less sharpness. When you screen compare, always check PPI. For phones, anything above 400 PPI looks sharp. For monitors used at desk distance, 100-140 PPI is the sweet spot. For TVs viewed from across a room, 50-80 PPI is fine.

✅ 3. Physical Dimensions and Weight

Screen size doesn't tell you the full device size. Bezel width, camera bumps, and form factor all add to the physical footprint. When comparing phones, check the full body dimensions:

The iPhone 16 Pro Max is 15.4mm taller and 56g heavier than the iPhone 16. That's the difference between a phone that's comfortable in one hand and one that absolutely requires two hands. Use the Easy Compare screen comparison tool to visualize these size differences before buying.

✅ 4. Viewing Distance and Room Size

The right screen size depends entirely on how far away you sit. A 65-inch TV is perfect for a living room with an 8-foot viewing distance, but overwhelming in a bedroom where you sit 4-5 feet away. For monitors, a 27-inch screen is ideal at 2 feet, while a 32-inch may feel too large at the same distance unless you push your desk back. See our TV size guide for room-based recommendations.

✅ 5. Aspect Ratio

The aspect ratio determines the shape of the screen. Most monitors and TVs are 16:9. Ultrawide monitors are 21:9. Modern phones are typically 19.5:9 to 20:9. When you screen compare, make sure you're comparing the same aspect ratio — or account for the difference. A 34" ultrawide and a 32" 16:9 have similar total areas but very different shapes, and they suit different workflows.

✅ 6. Panel Technology (OLED vs LCD vs Mini-LED)

Screen size tells you how big. Panel technology tells you how good. OLED screens have perfect blacks and infinite contrast — they look incredible for movies and gaming. Mini-LED screens get much brighter and are better for HDR content in bright rooms. Standard LCD/IPS panels are the most affordable and still look great for productivity. When you compare screens, factor in the panel type alongside size and resolution.

✅ 7. Refresh Rate

Refresh rate (measured in Hz) determines how smooth motion looks on screen. Standard is 60Hz. Gaming monitors offer 120Hz, 144Hz, 165Hz, or even 240Hz. High-end phones use 120Hz adaptive displays. TVs range from 60Hz to 120Hz. If you game or watch sports, prioritize 120Hz. If you mostly read and browse, 60Hz is fine.

✅ 8. Your Actual Use Case

The final — and most important — check. Match the screen to what you actually do:

• Reading & web browsing: Prioritize PPI (400+ for phones, 100+ for monitors). Size is secondary.
• Movie watching: Prioritize size and contrast (OLED). 65"+ for living rooms.
• Gaming: Prioritize refresh rate (120Hz+) and response time. 27" 1440p is the sweet spot for competitive gaming.
• Productivity & coding: Prioritize area and resolution. 27" 4K or 34" ultrawide at 1440p.
• Photo/video editing: Prioritize color accuracy (99%+ sRGB, 95%+ DCI-P3) and resolution. 27-32" 4K.

Quick Screen Compare by Device Type

Phones: 6.1" vs 6.7" vs 6.9"

The sweet spot depends on your hand size and usage. 6.1 inches (iPhone 16, Galaxy S25) is the best for one-handed use and pocketability. 6.7 inches (iPhone 16 Plus, Galaxy S25+) hits the balance between screen real estate and comfort. 6.9 inches (iPhone 16 Pro Max, Galaxy S25 Ultra) gives maximum screen area but demands two hands and a big pocket. Compare them visually with Easy Compare or see our 6.7 vs 6.9 inch phone guide.

Monitors: 24" vs 27" vs 32"

24 inches at 1080p is the budget pick — fine for basic office work. 27 inches at 1440p is the sweet spot for most people — sharp enough, large enough, affordable. 32 inches at 4K is ideal for immersive work, creative tasks, and those who want maximum screen real estate without going ultrawide. See our best monitor size for programming guide for more.

TVs: 55" vs 65" vs 75" vs 85"

For most living rooms with an 8-foot viewing distance, 65 inches is ideal. If you sit 6-7 feet away, 55 inches works. For dedicated home theaters or 10+ foot distances, go 75-85 inches. Always buy the biggest TV your room and budget allow — most people regret going too small, not too big. Use the what size TV do I need guide to calculate your ideal size.
