Card Saver 1 vs Card Saver 2

Card Saver 1 measures about 3 5/16 by 4 7/8 inches, and Card Saver 2 measures about 3 by 4 inches. That extra size on the 1 makes it the looser, easier holder to slide a card in and out of, and it's the specific style PSA's own submission instructions call out by name. Card Saver 2 is the snugger option, built for thin stock that would otherwise shift around inside the bigger holder. If you're prepping cards for grading and you're not sure which to buy, buy Card Saver 1.
The size gap, side by side
| Card Saver 1 | Card Saver 2 | |
|---|---|---|
| Approx. size | 3 5/16 x 4 7/8 in | 3 x 4 in |
| Fit | Looser, easy in and out | Snug, less room for the card to move |
| Best suited to | Standard modern cards | Thin or vintage stock |
| Named in PSA's submission guidance | Yes | No |
Why the extra size on Card Saver 1 matters
A looser holder is easier to load and unload without bending a corner against the opening, and it's forgiving of a card that's carrying a penny sleeve underneath it. That combination, a sleeve plus a standard modern card, is close to what most people are actually submitting, which is likely why it's the format PSA names specifically. The tradeoff is that a thin, older card can have a little more room to shift inside a Card Saver 1 than it would in the snugger Card Saver 2.
Where Card Saver 2 actually wins
Vintage cards and other thin stock are the case for Card Saver 2. A card with less body to it moves around more in a looser holder, and the snugger fit keeps it steadier during handling and shipping. The downside is the same tightness that makes it steadier: getting a card in or out without forcing an edge takes more care, and it's not the size PSA points to in its own instructions. If you're grading modern cards, that alone is reason enough to default to Card Saver 1 instead.
Does the size difference change how you sleeve the card first?
Not meaningfully. Either Card Saver size still expects a sleeved card going in, not a bare one, the same as a toploader. What changes is how much slack that sleeved card has once it's inside. A standard card in a penny sleeve has comfortable room in a Card Saver 1 and a tighter fit in a Card Saver 2, which is the whole reason the second size exists for thinner cards in the first place.
Which one for a grading submission
If you're submitting to PSA, Card Saver 1 is the safer default because it's the style their instructions describe, and it comfortably fits a standard modern card plus a sleeve. Save Card Saver 2 for vintage or unusually thin cards where the snugger fit is actually doing you a favor.

Quick answers
Which Card Saver does PSA want? Card Saver 1. It's the style named in their submission instructions, though you should check PSA's current guidance before you box up a submission, since exact requirements can be updated.
Is Card Saver 2 too small for a standard card? Not too small to fit, but tight enough that some collectors find it harder to slide a card in and out without care. It's built for thin stock, where that snugness is the point.
Can I use Card Saver 2 for a thick modern Pokemon or sports card? It's not the right choice. A thick card in a snug holder is a recipe for a crease at the opening. Stick with Card Saver 1, or size up to a rigid toploader for storage that isn't headed to a grader.
Do both sizes work the same way, sleeve first? Yes. Sleeve the card, then slide the sleeved card into whichever Card Saver size fits the job. Skipping the sleeve and going straight into either holder is how a card picks up scuffs from the plastic itself.
The size numbers look small on paper, a few tenths of an inch either way, but they decide two different jobs. Card Saver 1 is the general-purpose choice for anything modern. Card Saver 2 is a specialist tool for the thin, older cards that actually need the tighter fit.
