What Is the Sheetz 12-Inch Custom Sub?
The 12-Inch Custom Sub is the full-length version of Sheetz's build-your-own sub program, and it's the option most people reach for when they actually want to feel full afterward rather than just tide themselves over. You go through the same ordering process as the smaller size — choose your bread, pick a meat or combination of meats, add cheese, then work through the topping and condiment bar — but at double the length, there's simply more room to load it up without the sandwich falling apart in your hands. It's a common choice for anyone fueling up before a long drive, working a full shift, or bringing food home for later.
Because it's assembled fresh rather than pre-made, sizing up doesn't mean sacrificing the customization that makes these subs worth ordering in the first place — every topping and condiment choice you'd make on the 6-inch is still available here, just applied across a longer sandwich. A lot of regulars also treat the 12-inch as two meals instead of one: eat half fresh, wrap the rest, and it holds up reasonably well for a second sitting later in the day. That flexibility is really the core appeal of this size — it's less about needing to eat it all in one go and more about getting more usable food for a smaller price jump than ordering a second sandwich outright.
Price, Value & Why It Can Vary
The 12-Inch Custom Sub starts at roughly $6.99 for a basic build. That's meaningfully less than ordering two separate 6-inch subs would cost, which is the main reason it's considered the better value pick if you know a full-size sandwich is what you're after — you're paying for length, not restarting the base price twice.
From that starting point, the same variables that affect any custom sub apply: premium meat choices, extra cheese, and doubled-up toppings each add their own cost, and since those add-ons are priced per sandwich rather than per inch, a heavily loaded 12-inch can close some of the value gap versus the smaller size. Store location also plays a role in the base price, the same way it does across the rest of the Sheetz menu, so don't be surprised if the number at your local store differs slightly from what's listed here. Checking the app before ordering is the most reliable way to see the current price and catch any combo pricing that might apply.

As a fully build-your-own item, the calorie total depends entirely on what you select — a lean turkey build will land far lower than a double-meat, extra-cheese version. Check the Sheetz app or kiosk nutrition panel while building your sub for an accurate figure. See our full Nutrition & Calories guide for more items.
Why the 12-Inch Custom Sub Stands Out
- More room to build without falling apart. At double the length of the 6-inch, a fully loaded sub holds together better in your hands.
- Better value per inch. It's priced at less than double the 6-inch, so sizing up costs less than ordering two smaller subs.
- Works as two meals. Many customers eat half fresh and save the rest, since sub sandwiches generally hold up well stored for later.
- Same full customization at a bigger size. Every bread, meat, cheese and topping option available on the 6-inch carries over here, just applied across a longer sandwich.
How to Order This Item
In-Store Kiosk: Select "12-Inch Custom Sub" under the MTO tab, then move through the bread, meat, cheese and topping screens before it's assembled fresh.
Mobile App: Order ahead through the Sheetz app if you know you want the full-size build, and save your combination as a favorite for next time.
Delivery: Offered through partner delivery apps at many locations; wrapping half for later travels fine, though the sandwich is best eaten shortly after it's made rather than sitting for a long ride.
I started ordering the 12-inch specifically to split into two meals, and it genuinely works — the second half held up fine in the fridge overnight and didn't taste like a sad leftover the next day. Loading it up with double meat and extra cheese does test the bread a little, so I've learned to ask for sauce on the side if I'm not eating it immediately. For the price difference over the 6-inch, it's an easy call if you're hungry enough to actually finish it.
Quick Questions
Is the 12-Inch Custom Sub meant to be split between two people?
It's built as a single order, but plenty of customers do split it, especially when pairing it with sides. It also works well as one meal now and a second half saved for later, since sub sandwiches generally hold up well in the fridge.
Does the 12-Inch Custom Sub cost exactly double the 6-inch?
No, it's usually priced at less than double the 6-inch starting price, which is what makes it the better value per inch if you know you want a full-size sub. The gap narrows once you start adding premium meats or extra toppings, since those add-on charges apply per sandwich rather than per inch.
Does the 12-Inch Custom Sub reheat well?
It depends on the build — a sub with lighter toppings holds up fine stored and eaten cold or at room temperature, but heavier, sauce-loaded builds are best eaten fresh rather than reheated.
Can I choose different toppings on each half of the 12-Inch Custom Sub?
The standard build applies the same toppings across the whole sandwich, but you can ask for certain toppings, like extra sauce or pickles, to be added toward one end if you're planning to split it and want variety.
Is the 12-Inch Custom Sub available through the Sheetz app?
Yes. It can be fully customized and ordered through the Sheetz mobile app, the in-store kiosk, and delivery through partner apps where available.
