Screen Resolution Reference

The Screen Resolution Reference is a static cheat sheet. It lists the long-standing industry resolution names (HD, FHD, QHD/2K and 4K/UHD) with their pixel dimensions, aspect ratios and typical uses, plus rough typical ranges for a few device categories: laptops, full-screen phones and tablets. It does not detect your own screen's resolution and it doesn't list specific phone models. To read your own device's numbers, use this site's Device Info Detector tool.

How to read it

1. Each card on the page is one entry. The first line shows the name, the resolution (width × height in pixels) and the aspect ratio; the second line is a short note.
2. Find the name relevant to your task. For video work, responsive web styles or buying a monitor, the most common reference points are FHD (1920×1080) and 4K/UHD (3840×2160).
3. Look at the aspect ratio to understand the shape of the screen. In the table, HD, FHD, QHD, 4K and the common laptop are all 16:9, the phone entry is about 19.5:9 (taller and narrower), and the tablet is about 16:10.
4. Entries marked with 'around' or 'about', such as the phone's 'around 1080×2340', give a common range and should not be read as the exact spec of any model.
5. To check your own device, use the Device Info Detector tool instead of guessing from this table.

What's in the table

The page contains 7 entries: HD at 1280×720; FHD (Full HD) at 1920×1080; QHD/2K at 2560×1440; 4K/UHD at 3840×2160; a common laptop at 1366×768; a common full-screen phone at around 1080×2340; and a common tablet at around 1600×2560. The first five are all 16:9. A quick multiplication checks the pixel counts: 1920×1080 = 2,073,600 and 3840×2160 = 8,294,400, which is exactly four times as many. So 4K has four times the pixels of FHD (the page words this as 'four times the pixel density of FHD'; strictly speaking that equals density only when compared on the same physical screen size).

Supported range and known limits

• Only 7 fixed entries, with no search, filter or sorting, and no 8K, ultrawide (21:9) or Retina entries.
• The phone and tablet rows are 'rough ranges', not official standards, and real models vary widely by brand.
• No specific phone models are listed. That's a deliberate choice by the page to avoid going stale or being wrong when models change.
• The term '2K' isn't used consistently in the industry. The page groups it with QHD (2560×1440), but in film and video 2K sometimes means a different size (for example 2048 pixels wide). For production work, go by the exact pixel count.
• These are physical pixel counts. Web design uses CSS pixels, and on high-density screens one CSS pixel may map to several physical pixels, so a phone at 1080×2340 does not have a 1080-wide viewport for web layout.
• The page doesn't compute PPI (pixel density) or screen size and has no resolution converter.
• No date of last verification is given, so treat it as an introductory reference.

FAQ: How do FHD, 2K and 4K differ?

Per the page: FHD is 1920×1080, QHD/2K is 2560×1440 and 4K/UHD is 3840×2160. A bigger number means more pixels and potentially a finer image, but also greater demands on the graphics card, bandwidth and storage.

FAQ: Why doesn't my phone's resolution match the table?

The phone entry is only a common range, and manufacturers ship many other specs such as 1080×2400 or 1440×3200. To find your phone's actual numbers, use the Device Info Detector tool or look under About phone in your system settings.

FAQ: Which resolution should I design a website for?

A more practical approach is responsive design rather than fixating on one resolution. You can use this site's Device Simulator to preview your page at iPhone, iPad and desktop viewport widths. Physical resolution is only a reference; what really drives the layout is the CSS viewport width.

FAQ: What's the difference between 16:9 and 16:10?

16:9 is wider and flatter and is the mainstream ratio for TVs and most monitors; 16:10 is a little taller and more common on laptops and tablets. At the same width, 16:10 gives more vertical space, which suits reading and office work.
