Continuity mistake: Dan tells Crystal that his shoe size is 11. A few months later during episode 16, "Mall Story", Dan tells a shoe salesman he takes a size 13.
Suggested correction: Some people wear different sizes depending on the type of shoe. Not necessarily a mistake.
Continuity mistake: When a depressed Roseanne emerges from her bedroom after Dan has left her, she tells Nancy and Leon that she wants to turn over her and Jackie's shares of the restaurant to them. She says she wants Nancy and Leon to experience the same sense of accomplishment that she and Jackie felt when they first opened the business. However, Roseanne seems to have forgotten that it was Nancy, along with her, Jackie, and Bev, who started the restaurant.
Continuity mistake: In one episode, there is a bowl of fruit on the table in the living room. The boys start wrestling and they knock it down. In the next shot it's back on the table again, untouched.
Continuity mistake: During the show's first two seasons, we are told Roseanne had a more slender figure during her younger years and didn't start gaining weight until after she began having kids. Later in the Halloween episode, "The Ghost of Halloween Past," Roseanne is shown her past, and her younger versions are not slender.
Continuity mistake: In episodes when Darlene has just moved into her apartment, the bathtub is on the wall in front of the bathroom door. In later episodes, the tub is on the wall to the left of the door.

Brain-Dead Poets Society - S2-E10
Continuity mistake: When Roseanne starts to serve the plates of food at dinner, she hands Dan the first plate, but DJ already has one. When she serves the second plate of food and gives it to Darlene, a plate of food can be seen in front of Becky.
Continuity mistake: In the episode where Jackie takes over the house, while Roseanne is at their parents. DJ comes in the kitchen and is sent in the laundry area for a shirt. Before he goes in there he is wearing a pair of dark jean with nothing on them. He comes back a second later with his head stuck in a shirt still with the same pants on. But when he finally pops his head through the shirt his pants have changed to a pair of stonewash, with what looks like bleach stains on the front. A wide shot of the kitchen in the next frame and his pants are back to the dark ones with nothing on them.
Continuity mistake: Becky's braces disappear and reappear during shots in the kitchen.
Construction Junction - S8-E16

Continuity mistake: When Roseanne is talking on the phone to Jackie, she continually moves around the kitchen while preparing dinner. The extra-long phone cord goes from being completely wrapped around her waist to just being behind her, then wrapped around her again, without moving in a way that would unwind it.
Continuity mistake: Darlene and Becky's second-story bedroom window is on the side of the house and at the house's backside (D.J.'s room is at the front and the windows are also on the side). However, when the girls argue and throw each other's items out the window, everything falls into the front yard, as viewed from the living room. Even if they threw stuff from the house's front, the roof extends too far out below two smaller upper windows. Everything would land on the roof.

Continuity mistake: In Ziggy's first appearance in the series (S2, EP. 16 "Born to Be Wild"), he says he has two kids. He states "I had to make mine. I checked them at birth, they're boys!" However in his second appearance in the series here, he states they were his girlfriend, Jill's, kids and the kids are back living with their father.
Continuity mistake: When the girls are at the Lobo Jackie has a long scarf in her hair that moves between having the length of the scarf behind her back and then draped on her front left side.
