Lol, random question... not too sure this belongs in an Anime Forum (or even Pokemon Anime)...
Blaziken: 75 inches tall
Sceptile: 67 inches tall
Scale (or whatever it's called): (Ash&May's height) / 11 inches
Just divide the Pokemon's height with the scale. It depends on how tall Ash and May are to begin with. Assuming they're, say, 60 inches (5 feet) tall, then:
Blaziken would be 75 / (60/11) = about 14 inches tall
Sceptile would be 67 / (60/11) = about 12 inches tall
If I'm wrong, then let me just say in advance I'm sorry for ruining your little project. -_-;
i heard on some website ash and may are 5' 5" tall
Even though they should have been growing all this time, I doubt they're really as tall as 5'5'', and I also doubt any website that says that really knows what they're talking about. In any case, use whatever heights you want.
here one website about ash

Most of the info on that page is outdated. Anway, I don't think any official source ever announced a height for Ash at any point in time, and I think it's pretty obvious Ash didn't start the series at a height of 5'5'' like it's apparently implying (and he doesn't look it now, either). The anime has been pretty good about being ambiguous concerning any personal physical stats about any of its characters - be it age, height... or whatever.here one website about ash
