Here a few tips to help you gain that bigger chest.
There's no need to do dips and presses in the same workout. Just pick 1 and do 4-to-6 sets of 4-to-12 reps using a weight heavy enough to only allow you to do 4-to-12 reps.
If you want to do a variety of dips and presses in your chest workout then limit your workout to a total of 4-to-8 sets so for example…
You can do 3 sets of dips & 3 sets of bench presses or…
You can do 2 sets each of Incline, Flat & Decline Bench presses.
You only need to work out your chest 1-to-2 days per week for a bigger chest.
As your chest gets much bigger & stronger you may have to work out your chest less than once a week but if you're a pure beginner that's weak who's never done a lot of chest training…
You may be able to get away with training your chest up to 3 days a week while still progressively getting stronger each chest workout by using heavier weights, doing more reps and/or sets.
Save chest flyes for the beginning or end of your chest workout
You can pre-exhaust your chest muscles with chest flyes before dips and presses for a better chest workout or…
You can do flyes at the end of your chest workout to further tone & define your chest.
Keep a training log so you can keep track of how much weight, sets & reps you're doing so you can keep beating your last workout to help you get a bigger and stronger chest faster so for example…
If you did 5 sets of 10 reps using 225 pounds on the bench press then the next time you workout you want to beat your last workout by…
Doing at least 6 sets and/or…
Doing at least 11 reps and/or…
Using more than 225 pounds.

Don't overtrain or try to work your chest more than 2 times a week (more is NOT better) and it won't help you get a bigger chest faster because your chest muscles need to rest and recover so they can grow and…
If you're at a point where you're working out your chest more than 2 times a week but…
You're using the same amount of weight, reps and sets each workout then you're wasting your time because you can't get bigger & stronger doing the same workout over & over without using more weight, reps and/or sets so…
Make sure that you rest long enough (at least 2-to-3 days) in between chest workouts so you can beat your last workout by using more weight, doing more reps and/or sets
