6 Inch vs 12 Inch Sub (and 8 Inch): Which Size to Pick?

The 6 inch vs 12 inch sub question comes down to one fact: a 12" is the full roll and a 6" is half of it. At Tiffins ToGo, inside Urban Center Market, 387 E Las Colinas Blvd, Suite 106, Irving, TX 75039, our 12" sandwiches are built on a 12" roll and our 6" sandwiches on half of that roll. We also offer an 8" size in between. This guide shows what changes between sizes, what each costs, and how to pick, using our three melts: the Grilled Chicken Melt, the Turkey Club and the Cheesy Beef Melt.

6 inch vs 12 inch sub: how much bigger is the 12 inch?

A 12" sandwich is twice the length of a 6". Since our 6" is half of the 12" roll, the bread doubles when you go up. That is the simple part. What matters more is the price, because the 12" does not cost twice as much.

What does each size cost?

In-store prices from our menu. Combo upgrade to a 24 oz smoothie is $2 more. The Hummus Wrap is $8.95 in store. Prices on DoorDash and Uber Eats may differ.

What does a bigger size save?

Two 6" sandwiches cost more than one 12" of the same kind. For example, two 6" Grilled Chicken Melts are $16.98 and one 12" is $14.99. If two people want the same sandwich, one 12" cut in half saves money. If they want different sandwiches, two 6" sandwiches let each person choose. The 8" gives you a third more roll than the 6" for a small step up in price, which is why it suits a bigger lunch for one person.

When should I order a 6 inch?

• You want a lighter lunch.
• You are adding a side, like a smoothie or a small box of wings.
• You want to try a sandwich for the first time before going bigger.

When should I order the 8 inch?

The 8" is for the in-between appetite. It is a regular lunch for most people who find a 6" too small but do not want a full 12". On price per inch, it is the lowest of our three sizes for every melt.

When should I order a 12 inch?

• You are very hungry, or this is your main meal of the day.
• You are splitting it with one other person.
• You want leftovers for later. Note that the cold toppings are on the sandwich, so it is best eaten soon.

Does the build change with the size?

The recipe and the order of layers stay the same at every size. The sauce goes on the bottom half, then the hot meat and provolone go into the oven while the top half toasts beside it. After a short rest, we add tomato, dressed greens and the sandwich's own toppings, then the top sauce. A bigger size means more of each layer along a longer roll, not a different sandwich.

What about the combo?

The Sandwich Combo is any size sandwich plus a 16 oz smoothie: $13.49 with a 6", $14.95 with an 8" and $19.99 with a 12" in store. Upgrading the smoothie to 24 oz is $2 more. If you want a smoothie anyway, check the combo price before adding items one by one.

Ordering for a few people at once?

Size math matters more when you order for three or four people. A simple plan: one 12" per two people who agree on a sandwich, and a 6" for anyone who wants something different. Add a 16 oz smoothie for each person who wants one, or check if a combo comes out lower. If you are ordering on DoorDash or Uber Eats, add a note asking us to cut the 12" sandwiches in half, so they are easy to hand out. For larger office orders, see our group orders page.

Does a bigger sandwich stay hot longer?

A longer sandwich holds a little more heat, but every size gets the same treatment. The hot layer is the meat and provolone from the oven. The cold layer, tomato and greens, goes on after. So the sandwich is warm in the middle and crisp on top at any size. For pickup, the best bite is right away. For delivery, the toasted roll keeps the sauce from soaking through.

Where can I read more about each sandwich?

This post is only about size. For what goes in each sub, see the product pages for the Grilled Chicken Melt, the Turkey Club and the Cheesy Beef Melt, or read sub sandwiches in Irving TX and our guide to oven toasted sandwiches near me. Our hours and location page has the map.

Common size mistakes

• Ordering two 6" sandwiches of the same kind when one 12" costs less.
• Ordering a 12" for one person at lunch, then saving half that sits with cold toppings on it.
• Skipping the combo when you planned to buy a smoothie anyway.

Key takeaways

• A 12" sub is twice the length of a 6", and the 8" sits in between.
• The recipe and layer order are the same at every size.
• One 12" costs less than two 6" sandwiches of the same kind.
