Chances were few and far between and a point did little to calm the nerves of the FA Cup semi-finalists, who remain embroiled in a tight battle to avoid dropping out of the Championship.
Jackett said: "I felt that we had the better of the chances - Ipswich had a couple but we had more that were clear-cut.
"Since the (FA) Cup quarter final we've won two games and drawn one, but the gap's closed at the bottom over this Bank Holiday weekend
"I felt today that we generally lacked width, even early on in the game until Ipswich just matched us up.
"Early in the game, I felt that even though we passed the ball well, we lacked players that could go past people. I probably should have introduced Liam Feeney earlier on because he did have a positive effect when he came on.
"Looking at our squad, we've got James Henry and Chris Taylor who are very capable of beating a man, putting good balls into the box and stretching sides who were unavailable.
"If there's any criticism of us we lacked width and we really needed it today."
