Subway Footlong vs 6 Inch - Calories, Protein, And When To Choose Each
Compare Subway footlong vs 6 inch sandwiches. See exact calorie, protein, and macro differences plus when each size makes sense for your goals.
A Subway footlong has almost exactly double the calories, protein, carbs, and sodium of the same 6 inch sub, so portion size is the main difference between them. There's no nutritional magic - a footlong is simply two 6 inch subs in one.

The Simple Math
For any Subway sandwich:
- Footlong Calories = 6 inch × 2
- Footlong Protein = 6 inch × 2
- Footlong Carbs = 6 inch × 2
- Footlong Fat = 6 inch × 2
- Footlong Sodium = 6 inch × 2
This applies to everything: cheese, sauce, vegetables - all doubled.
When A 6 Inch Is The Smarter Choice
1. Weight Loss Goals
If you're targeting 400-600 calories per meal, a 6 inch fits perfectly. Most footlongs exceed 600 calories before adding cheese or sauce.
2. Calorie Deficit Days
Saving a footlong for "later" rarely works. Most people eat the whole thing. A 6 inch with water is a complete meal under 400 calories.
3. Part Of A Larger Meal
If you're adding soup, salad, or a side, 6 inch prevents overconsumption.
4. Sodium Concerns
Footlongs can contain 1,600-3,000mg sodium - exceeding daily limits in one meal. A 6 inch keeps sodium more manageable.
5. Budget Watching
A 6 inch costs less, and the "value" of a footlong disappears if you don't need the extra calories.
When A Footlong Can Fit Your Goals
1. High Protein Needs
Athletes and those building muscle may need 40-60g protein per meal. A footlong rotisserie chicken delivers 52g.
2. Meal Prep / Two Meals
Buy a footlong, eat half now, refrigerate half for later. This works if you have the self-control.
3. High Calorie Requirements
Bulking, very active individuals, or those with high metabolisms might need 800-1,200 calorie meals.
4. Sharing
A footlong split between two people equals two 6 inch subs with potential cost savings.
5. Intermittent Fasting
If you eat in a compressed window, a footlong might fit your macro targets in fewer meals.
Splitting A Footlong Into Two Meals
If you plan to split a footlong:
How To Do It Right
- Order the footlong
- Ask for it cut in half (they'll do this anyway)
- Get separate wrapping for each half
- Refrigerate the second half immediately
- Eat within 24 hours for best quality
Best Subs For Splitting
- Turkey Breast - Stays fresh, doesn't get soggy
- Ham - Keeps well refrigerated
- Rotisserie Chicken - Good cold or reheated
Worst Subs For Splitting
- Meatball Marinara - Gets soggy quickly
- Tuna - Texture suffers after hours
- Anything with lots of sauce - Bread absorbs sauce and gets mushy
Cost Comparison
| Item | Typical Price | Per Inch |
|---|---|---|
| 6 inch | ~$7-9 | $1.16-1.50 |
| Footlong | ~$10-14 | $0.83-1.16 |
Footlong saves ~$3-4 if you genuinely need the full amount or will split it properly.
But: If you eat a footlong when you only needed 6 inches, you've spent $3 extra on calories you didn't need.
Nutrition Per Dollar
| Option | Cost | Calories | Protein | Cal/$ | Protein/$ |
|---|---|---|---|---|---|
| 6" Turkey | ~$8 | 290 | 19g | 36 | 2.4g |
| FL Turkey | ~$12 | 580 | 38g | 48 | 3.2g |
| 6" Rotisserie | ~$9 | 320 | 26g | 36 | 2.9g |
| FL Rotisserie | ~$13 | 640 | 52g | 49 | 4.0g |
Footlongs offer better value per calorie and protein, but only if you need those amounts.
