Apex Percent Usage

I wanted to check on how is Apex code counted towards the limit, considering we are only allowed 6,000,000 characters (6 MB ) and we might come across a situation where we may want to increase the aforementioned limit.

Salesforce allows you to increase limit upto 10,000,000 characters (10MB) on logging a case.

Salesforce doc

I have created a few scenarios to check on what all simple things contribute towards this usage.

After creating a dummy class below is apex usage, we would run different scenarios on below class to see how is apex usage changed.

	public class test{
	public String firstVar;
	public String secondVar;
	}

• Adding redundant new lines (/n) in the code doesn't impact the usage.

	public class test{
	public String firstVar;
	public String secondVar;
	}

• Adding redundant spaces/tab in between the code increases the usage.

	public class test{
	public String firstVar;
	public String secondVar;
	}

• Adding redundant spaces/tab even at the end of line increases the usage.

	public class test{
	public String firstVar;
	public String secondVar;
	}

• Adding spaces/tabs for indentation of code also seems to increase the usage(for demo purposes I have indented class variables only)

	public class test{
	public String firstVar;
	public String secondVar;
	}

• Adding comments in class don't impact the usage.

	// This is the dummy class I have created to check Apex usage
	public class test{
	// first variable
	public String firstVar;
	// second variable
	public String secondVar;
	// end of variables
	}

• Creating a test class don't count towards apex usage ie redundant tabs/spaces none of them are counted.

	@istest
	private class testClass{
	@isTest static void testName() {
	Account a = new Account(name='test Account');
	insert a;
	}
	}

• Blank lines containing only spaces are also not counted towards the usage.

	public class test{
	public String firstVar;
	public String secondVar;
	}

Note : Managed packages are not counted towards the limit as they belong to different namespace as that of your org.
