List of Pokémon by sprite size in Generation I

This is a list of Pokémon by sprite size in Generation I.

Technical details

In the Generation I games, the field 0x0A of the Pokémon species data structure is a single byte which contains the Pokémon's front sprite dimensions. This is also found as the first byte of each Pokémon's compressed sprite image. The high and low nybbles correspond to the width and height in tiles, respectively. Each tile is 8×8 pixels.

Available sprite sizes:

• 5×5 tile sprites (40×40 pixels) are centralized at the bottom, with blank spaces at the top (2 tiles high), left (1 tile wide), and right (1 tile wide). Each sprite's uncompressed size in the 2BPP (2 bits per pixel) format is exactly 400 bytes. Their hexadecimal ID is 0x55.
• 6×6 tile sprites (48×48 pixels) are located in the bottom-right corner, with blank spaces at the top (1 tile high) and left (1 tile wide). Each sprite's uncompressed size in the 2BPP (2 bits per pixel) format is exactly 576 bytes. Their hexadecimal ID is 0x66.
• 7×7 tile sprites (56x56 pixels) occupy the entire sprite area. Each sprite's uncompressed size in the 2BPP (2 bits per pixel) format is exactly 784 bytes. Their hexadecimal ID is 0x77.
