Eng:Overriding the Costume Size Limit

Scratch imposes limits on both the maximum and minimum size of a sprite depending on the dimensions of its costume. For the default Scratch Cat, this is between 5 to 535 percent. For a single pixel, it is 100 to 54,000 percent. For a costume the size of the stage (480x360), it is 1 to 150 percent. This tutorial explains how to circumvent this limit.

Tutorial
To make a sprite larger than allowed, create a 1x1 costume after your original, then apply these scripts: when gf clicked set [costume v] to (costume #) switch to costume [dot v] //this is the 1x1 costume which allows a large size set size to (...) //insert a large value switch to costume [A costume v] //the previous size remains when switching to the larger costume

Another way is to use a custom block: define Super Big (LargeSize) set [costume v] to (costume #) switch costume to [dot v] //The 1x1 dot set size to (LargeSize) switch costume to [A costume v]

This can be very useful for scrollers.
