In computer graphics and video images, the pixel resolution is the number or pixels in the display. Resolution describes the detail an imageholds. The term applies equally to digital images, film images, and other types of images.  

Texture resolutions must be in what is known as a Power of Two. This is the number of “blocks” or pixels, Scales up (and down) nicely in binary calculation like 1, 2, 4, 8, 16, 32, and 64.

The more common texture resolutions are as follows: 

256*256=256 kb

512*512=1 MB

1024*512=2 MB

1024*1024= 4 MB

2048*1024=8 MB

2048*2048=16 MB

4096*4096 =64 MB 

Films require high resolution textures and its counting is done in 1k, 2k, 3k, and 4k. 

1024*1024= 1 K

2048*1024=2 K

2048*2048=3 K

4096*4096 =4 K

Games require low resolution textures because of its real-time processing of render engine. Like 32, 64, 128, 256, 512 pixels.

Compositing also require high resolution images as matte painting, BGs and high color quality data.

Print requires high resolution images starting form 150 dot per inch resolution.

Apart from these pixel calculations you can also define resolution of image depending on hardware medium you are using. For example if Film is transferring to DI, it produce blur whereas if transfer is done from Beta Tape to DI then no problem occurs. This is a list of modern-day, digital-type measurements (and traditional, analog horizontal resolutions) for various media. The list only includes popular formats, not rare formats, and all values are approximate (rounded to the nearest 10), since the actual quality can vary machine-to-machine or tape-to-tape. For ease-of-comparison, all values are for the NTSC system. (For PAL systems, replace 480 with 576

  • 35 mm film
  • 35 mm original camera negative motion picture film can resolve up to 6,000 lines.
  • 35 mm projection positive motion picture film has about 2,000 lines which results from the analog printing from the camera negative of an interpositive, and possibly an internegative, then a projection positive.
  • Sequences from newer films are scanned at 2,000, 4,000 or even 8,000 columns (line measured the other directions), called 2K, 4K and 8K, for quality visual-effects editing on computers.

Rendering for film and HDTV need high-resolution textures

High Definition usually refers to 720 or more lines of video format resolution displayed in a horizontal fashion from top to bottom.

The best resolution of a texture is the double size of the corresponding image. Or to be more precise: the final size of the corresponding object in the final image, for example texture a Box that will have a size of 100×100 pixels in a 1000×1000 pixels rendering, your texture should have a resolution of around 200×200 pixels. Anything below this level will cause a blur effect; anything above it will be useless at one point since the details are not “spotted” anymore by the render engine.
