Hello, each row consists of frames of 32 pixels height and 48 pixels width, if you need the entire row dimensions then you could count how many sprites are per row and multiply it by 48 and it will be the row width in pixels, as for height is still 32 pixels for each row.
Also I updated the file, and included a folder with each animation splitted in individual sprites, so that things could be more flexible..)))
thank you for your support!
