What is 1440p resolution?

1440p is a progressive frame 2560 pixels wide and 1440 pixels tall (2,560 × 1,440 = 3,686,400 pixels) at a 16:9 aspect ratio. It is usually called QHD (Quad HD) or WQHD because it has four times the pixels of 1280 × 720 (each axis doubled).

What are the dimensions of 1440p?

Standard 16:9 1440p is 2560 × 1440 pixels (width first); vertical 1440p video is 1440 × 2560. Ultrawide 1440p monitors are 3440 × 1440 (about 21:9) and super-ultrawide ones 5120 × 1440 (32:9). The physical size depends on the diagonal: a 27-inch 16:9 panel is about 23.5 × 13.2 inches.

What bitrate should I use for 1440p?

YouTube recommends 16 Mbps for 1440p SDR uploads at 24–30 fps and 24 Mbps at 48–60 fps, and 20 Mbps and 30 Mbps for HDR. Those are upload recommendations, not universal quality targets; the right bitrate depends on codec, frame rate, motion and destination.

How much storage does one hour of 1440p video take?

Size = bitrate × seconds ÷ 8. At 16 Mbps, 16 × 3,600 ÷ 8 = 7,200 MB, or 7.2 GB per hour; at 24 Mbps it is 10.8 GB. Audio, container overhead and variable bitrate make the real file slightly different.

Is 1440p better than 1080p for gaming?

1440p renders 78% more pixels than 1080p, so the image is sharper at the same screen size: a 27-inch 1440p monitor is about 109 PPI against 82 PPI at 1080p. The cost is GPU load, which scales roughly with the number of pixels shaded, so frame rates drop unless the game is CPU-limited.

What is the PPI of a 1440p screen?

PPI = √(2560² + 1440²) ÷ diagonal = 2,937.2 ÷ inches. A 24-inch 1440p monitor is 122.4 PPI, 27 inches 108.8 PPI and 32 inches 91.8 PPI. A 34-inch 3440 × 1440 ultrawide is 109.7 PPI.

How far should I sit from a 27-inch 1440p monitor?

At about 32 inches (0.80 m) one pixel of a 27-inch 1440p panel subtends one arcminute, the limit of 20/20 acuity. Typical desk distances of 24–30 inches are slightly closer, so pixels can just be resolved; a 27-inch 4K panel moves that point to about 21 inches.

How does 1440p compare to 4K in file size?

4K UHD has 2.25 times the pixels of 1440p, but file size is set by bitrate, not resolution. YouTube recommends 35–45 Mbps for 4K at 30 fps against 16 Mbps for 1440p, about 2.2–2.8 times more data per minute.

What aspect ratio is 1440p?

2560 × 1440 is exactly 16:9 (both divide by 160), the same shape as 1080p and 4K UHD. 3440 × 1440 reduces to 43:18 (2.39:1) and is sold as 21:9; 5120 × 1440 is exactly 32:9.

Is 1440p the same as 2K?

Not technically. The DCI 2K cinema container is 2048 × 1080, while standard consumer 1440p is 2560 × 1440. Because 2560 horizontal pixels are closer to 2.5K, QHD or 1440p is the clearer name even though some retailers loosely call it 2K, and YouTube labels its 1440p option "2K".

Does 1440p require HDMI 2.0 or DisplayPort 1.4?

It depends on refresh rate and bit depth. 2560 × 1440 at 144 Hz with 8-bit color and reduced blanking needs about 14.1 Gbps of video data, which fits HDMI 2.0 (14.4 Gbps) and DisplayPort 1.2 (17.28 Gbps); 240 Hz needs about 24.6 Gbps and therefore DisplayPort 1.4 or HDMI 2.1. Check the monitor and GPU specifications for the exact mode.

Quick answer

1440p resolution is 2560 × 1440 pixels: 3,686,400 pixels (about 3.7 megapixels) at 16:9, called QHD or WQHD. It has 1.78× the pixels of 1080p and 0.44× those of 4K UHD. Ultrawide 1440p is 3440 × 1440 and super-ultrawide is 5120 × 1440.

Examples

1440p screen	Pixel density	20/20 distance
24-inch 2560 × 1440	122.4 PPI	28 in (0.71 m)
27-inch 2560 × 1440	108.8 PPI	32 in (0.80 m)
32-inch 2560 × 1440	91.8 PPI	37 in (0.95 m)
34-inch 3440 × 1440	109.7 PPI	31 in (0.80 m)

Enter your own screen size for its exact 1440p PPI and viewing distance, or a bitrate for file size.

Summary

1440p, commonly called QHD (Quad HD) or WQHD, uses a frame size of 2560 × 1440 pixels — exactly 3,686,400 pixels per frame — at a 16:9 widescreen aspect ratio. That is four times 720p and 1.78 times 1080p, and 0.44 times 4K UHD. This page calculates PPI, pixel pitch, 20/20 viewing distance and bitrate-based file size for 16:9 and ultrawide 1440p screens, lists official YouTube SDR and HDR upload bitrates, and compares 1440p with 30 other resolutions in a sourced table you can search, sort and download.

How it works

Pick a 1440-line format (16:9, 21:9 ultrawide or 32:9) or type any width and height.
Enter the screen diagonal for PPI, pixel pitch and the distance at which one pixel subtends one arcminute (20/20 acuity).
Enter a bitrate and duration for a decimal-GB file size (bitrate × seconds ÷ 8).
Check the official YouTube 1440p SDR and HDR upload bitrates before exporting.
Search or sort the resolution table to compare 1440p with 30 display, video and cinema formats, or download it as CSV.
