Because of the ' tab ' between words.
For example: 1xtab 2xtab 3xtab 4xtab 5xtab
Edit: Noticed that this forum version doesnt show the tab , test it by press
Dunno if you'll get what I mean or not , but , SQL customize any text into tables / rows with these tabs . So , if you'll take a look on the bigger size and , recopied it again then moved into text as you've done there.. size won't be changed because its already contains same customized tabs by sql.
