Try this piece of code it works fine

 -(float)getHeightByWidth:(NSString*)myString:(UIFont*)mySize:(int)myWidth

 {

CGSize boundingSize = CGSizeMake(myWidth, CGFLOAT_MAX);
CGSize requiredSize = [myString sizeWithFont:mySize constrainedToSize:boundingSize lineBreakMode:UILineBreakModeWordWrap];  
return requiredSize.height;
}

You can use NSString's -sizeWithFont:constrainedToSize:lineBreakMode: method to calculate the space a given amount of text would occupy.
