Possible Suggestion/Solution #1

    global static List<Account> getAccounts() {
       List<Account> accounts = [select id, name from Account];
        return accounts;

The code above just does the JSON serialisation that SF is going to do automatically, but does it before hand and logs it out to the debug log. It's a bit wasteful and really only for informal checking

Realistically, I would use Curl from the command line as documented here:

You can look at the Content Length HTTP header to get the length of the response body in bytes. In Workbench REST Explorer, click on Show Raw Response to see the headers on the right hand side of the output.

Can you try this

convert the responsebody to a string ( RESPONSE Body (corrected ) is a blob use .tostring())

string name = 'hello this is a test message to find bytes of the string ';
blob encode = EncodingUtil.base64Decode(name);
system.debug('%%%%' + encode.size());


Execute Anonymous: string name = 'hello this is a test message to find bytes of the string';
Execute Anonymous: blob encode = EncodingUtil.base64Decode(name);
Execute Anonymous: system.debug('%%%%' + encode.size());

10:51:47.092 (92605000)|VARIABLE_ASSIGNMENT|[1]|name|"hello this is a test (36 more) ..."
10:51:47.092 (92619000)|STATEMENT_EXECUTE|[2]
10:51:47.093 (93020000)|SYSTEM_METHOD_ENTRY|[2]|system.EncodingUtil.base64Decode(String)

10:51:47.093 (93469000)|VARIABLE_ASSIGNMENT|[2]|encode|BLOB(33 bytes)

10:51:47.093 (93676000)|SYSTEM_METHOD_ENTRY|[3]|System.debug(ANY)
10:51:47.093 (93693000)|USER_DEBUG|[3]|DEBUG|%%%%33
10:51:47.093 (93702000)|SYSTEM_METHOD_EXIT|[3]|System.debug(ANY)
