10KB is the file size, so it is impossible to determine what size it is. KB is the unit of measurement and storage, so it is impossible to judge the length, width and size of a photo.

10KB is the file size of the photo and cannot be used as a basis for judging the photo size. So only 10KB can't judge the size of the photo.

The size of photos is usually in inches, 1 inch ≈ 2.54 cm.

Extended data:

According to the SI standard, 1KB = 1024b (bytes, bytes), while according to the IEC standard, 1KB = 1024 b. When buying broadband, operators often refer to Mbps, which is megabits per second. According to the conversion of 1b = 8b, the actual speed of 100Mbps broadband is 12.5 MB/s, and the accurate value is about11.92 MIB/s.

However, the photo of 10KB seems too small to see the characters clearly. The photo size of 100-200 KB is normal.
