Quick answer: A Jersey Mike's regular sub runs about 7 to 8 inches and a giant runs 14 to 15 inches, close to double the length. A giant typically costs less than buying two regulars of the same sub, making it the better value if you're feeding more than one person. For a single meal without leftovers, regular is still the simpler choice.
Regular and giant look like a straightforward size upgrade, but the real comparison, on both size and price, is more interesting than "giant is just bigger." Here is what actually changes between the two, based on measurements and pricing reported across multiple sources plus Jersey Mike's own nutrition data.
The standard, single-serving size most Jersey Mike's combos are built around.
Roughly double the length of a regular, made from a full loaf rather than a half loaf.
Reported measurements vary slightly depending on the source and the specific location, some list regular closer to 6.5 to 7 inches, others 7 to 8 inches, but the giant is consistently described as 14 to 15 inches across independent reports. The practical takeaway is the same either way: giant is close to double the length of regular.
The Jersey Mike's regular sub size lands in the 7 to 8 inch range on fresh-baked bread, close to the classic foot-long comparison other sub chains use as their baseline, just slightly shorter. It's built as a single-loaf portion rather than the half-loaf-per-person math the giant uses, which is why it's the size most of the numbered combos are designed and priced around. For one person eating a full meal in one sitting, regular sub size hits the sweet spot: enough bread-to-filling ratio for a satisfying lunch or dinner without the leftovers a giant almost always creates. If you've mostly ordered mini or giant and want to know what the true middle size looks like, regular is that middle size, not scaled up or down for sharing, just built for one.
Length-wise, yes, close enough. But "double" is not always exact when it comes to filling. Independent calorie trackers put a regular Number Four at around 780 calories, while giant versions of the same sub are listed anywhere from about 1,480 to 1,530 calories depending on which tracker you check, a gap of roughly 80 to 100 calories short of a true double. The trackers do not fully agree with each other, which is common with third-party nutrition databases that pull from slightly different snapshots of the menu, so treat these as a reasonable range rather than an exact figure. For the current official numbers, check Jersey Mike's own nutrition page directly, since that reflects their current standardized recipes rather than a third-party estimate.
Pricing varies significantly by market since every location is independently franchised, but the general pattern reported across food publications and customer accounts is consistent: a giant sub typically costs less than buying two regulars of the same sandwich, even though it is not usually a perfect 50 percent discount. We were not able to independently verify a single current price example that holds across markets, so rather than cite one franchise's numbers as if they were universal, the more reliable move is to check your own store's app or menu board and do the math yourself: add up two regulars, compare it to one giant of the same sub.
Length and total price only tell part of the story. Price per inch shows which size actually stretches your money furthest, using a Turkey and Provolone sub as the common example across multiple sources:
| Size | Approx. length | Price per inch |
|---|---|---|
| Mini | 4-5 inches | Around $1.65 |
| Regular | 7-8 inches | Around $1.57 |
| Giant | 14-15 inches | Around $1.28 to $1.37 |
By this measure, giant consistently comes out as the best value per inch, with regular a reasonably close second and mini the most expensive per inch across every source that breaks the numbers down this way. This is the exact size comparison our homepage points to when it talks about price-per-inch across sizes.
Yes. Most locations will cut a giant sub in half or into fourths on request at no extra charge, which makes it a genuinely practical way to split a meal with someone else, or portion it out across two separate sittings if you are eating alone and do not want to finish 14 to 15 inches of sub in one go.
If you are eating alone and want one complete meal with nothing left over, regular is the simpler, less wasteful choice, and the price-per-inch gap versus giant is small enough not to matter for a single serving.
If you are feeding two or more people, want leftovers for a second meal, or are ordering for a group that can split a sub, giant is the better deal on a pure cost basis. The math consistently favors it over buying two separate regulars, and you can have it cut into portions on the spot.
A regular sub runs roughly 7 to 8 inches, while a giant runs 14 to 15 inches, close to double the length. Exact measurements vary slightly by source and by location.
Close, but not exactly. Independent calorie trackers put a giant sub at roughly 80 to 100 calories short of double the regular version of the same sandwich, so it is very close to two regulars but not always a perfect match. Check Jersey Mike's own nutrition page for current official figures.

Order regular if you're eating alone and want a complete meal without leftovers. Order giant if you're feeding two or more people, want leftovers for later, or want the better price per inch.
