Can somebody tell me about weight the differences of dumbell bench press and barbell bench press?

[Vivaldi]

I am doing dumbell bench press at home so I have no idea how much weight I can do barbell bench press. With a pair of 24.25 kilograms dumbells, I do 3 sets, Reps are 5-4-4. In first set I do 5 reps. A pair of 24.25 kilograms dumbells mean 48.5 kilograms total weight. But it is said that dumbell bench press is more difficult than barbell bench press so it is like I could use heavier weight if I did barbell bench press. How much differences will it be? How much weight do you suppose I would lift if I did barbell bench press for 5 reps? I guess the weight will be more than 48.5 kilograms because barbell bench press is eaiser than dumbell bench press? For example what would it be? 52-53 kilograms for 5 reps?

Right, they are different. The dumb bell is harder to control and works your sides and forearms more since you have to swing them up from the sides and up at the same time. Regular bench press is more just a straight up motion, so you can generally do about twice as much weight. If you are not sure, start out light and work your way up in weight. Also, use a spotter.
