hi try something like this in apex controoller in attachment method
 
if(attachment.size > 5242880){ 
          //maximum attachment size is 5MB.  Show an error
           ApexPages.addMessage(new ApexPages.Message(ApexPages.severity.Error, 'A "' + folderName0 + '" file was NOT uploaded, because it is too big (' + Decimal.valueOf(att0size/1048576).setScale(1) + ' MB): ' + att0name)); 
}

Hi @Karthikeyan Chandran,

Implement your code
Blob MyBlob=attachment.body;
          if(MYBlob.size()>5242880)  
            {   ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.WARNING, 'This file exceeds the maximum size limit of 5 MB.'));}
       
        
    }
