Using 4" jigsaw blades in place of 2.5" originals

i have a 20 plus year old black and decker jigsaw. i never replaced the blade as it didnt get used much. but now i need it for a few things. i went to the store not knowing what i had and guessed i did have set screw so got the u shank. but i didnt know how long my blade at home was so i just took what he gave me . which was 4 inch

before i rip open the 10 dollar pack i want to know if the 4 inch will work. i guess i worry thats more depth than i need and there's no way to adjust the depth.

It's more depth than you needed and you payed extra for that depth but they'll work fine for you.

There is no adjusting the depth on a jig saw.
What is it you plan on doing with it?
Whole lot of different blades for different jobs.

It will totally depend on the thickness of wood you will be cutting. With the shorter blades, you will encounter pop up, while the longer blades will stay below the materials and not hit it when it is in an up stroke. Note the depth of the blade when it is at its highest point. Compare that to the material you will be cutting.

If your jig saw has the ability to tip to cut at an angle you will need the longer blade. I wouldn't consider a 4" blade to be excessive long.

Longer Blade

Be mindful of pipes, wiring, or other obstructions which might be struck by the longer blade. Otherwise, no problem.
