The classic Arby’s crispy fish sandwich has about 65 g of carbohydrates; bun, sauce, and limited-time builds change the final count.
Chasing carbs at a sandwich shop can feel tricky, but it doesn’t have to be. This guide breaks down the carbohydrate numbers for Arby’s fish options, shows where the grams come from, and gives simple ways to trim the total without losing that crunchy, tangy bite.
Carbohydrates In Arby’s Fish Sandwich: What Changes The Count
When people mention the fish sandwich at Arby’s, they usually mean the classic crispy fillet on a sesame bun with tartar and lettuce. That build lands around 65 g carbs for a full sandwich, based on widely reported nutrition figures for the seasonal fish offering. The total moves up or down with three levers: the bun, the sauce, and any extras layered on top.
- Bun: The 4-inch sesame seed bun contributes a large chunk of the carbohydrate load at about 35 g carbs on its own (Arby’s official nutrition guide lists the 4″ sesame bun at 35 g total carbohydrates). If you swap or remove the bun, the total drops fast.
- Sauce: Tartar sauce adds a small but real carb bump. A standard tablespoon of tartar is roughly ~2 g carbs. Extra sauce or a double smear can nudge totals higher.
- Extras: Lettuce and tomato add very little. Cheese slices contribute almost no carbs, while sweet sauces or specialty buns add more.

Table #1 (within first 30% of article): broad and in-depth, <=3 columns, 7+ rows
| Item / Build | Total Carbs (g) | Notes |
|---|---|---|
| Crispy Fish Sandwich (standard build) | ~65 | Classic sesame bun + fillet + tartar + lettuce. |
| King’s Hawaiian Fish Deluxe | ~74 | Limited-time build on sweeter bun; higher carbs. |
| Crispy Fish Sandwich, No Bun | ~29 | Bun removed; fillet + toppings only. |
| Standard Sandwich, No Tartar | ~63 | Skips ~2 g contributed by tartar. |
| Standard Sandwich, Extra Tartar | ~67–69 | Two extra tablespoons add ~4–6 g carbs. |
| Standard Sandwich, Add Cheese | ~65 | Cheddar slice adds negligible carbs. |
| Standard Sandwich, No Bun + Lettuce Wrap | ~30 | Leaf lettuce is near zero carbs. |
| Standard Sandwich, Add Tomato | ~66 | Two tomato slices add ~1–2 g carbs. |
| Standard Sandwich On Different Bun | Varies | Specialty buns tend to raise carbs vs. the 4″ sesame. |
Why do these shifts matter? Because the bun can account for over half of the total carbs. Sauce is a smaller lever, but it stacks quickly if you like an extra-saucy sandwich. Toppings move the needle only a little, so they’re great places to add flavor without loading grams.
Where The Carbs Come From
The Bun Drives The Biggest Swing
Arby’s lists a 4″ sesame seed bun at ~35 g carbs and about 210 calories in its public nutrition guide. That single element can take a fish sandwich from a moderate low-30s tally (no bun) up to the mid-60s (with the bun in place). If a limited-time version uses a sweeter or larger roll, totals climb further.
Tartar Sauce Adds A Small Bump
Classic tartar is mayo-based with relish and seasonings. A tablespoon typically adds around ~2 g carbs. One serving keeps the total tidy; extra servings add up fast, especially on sweeter buns.
Breading And Fry Affect Only Part Of The Total
The crispy fish fillet itself contributes some carbohydrates through the breading, though much less than the bun. This is why a bun-free build can land near the high-20s to low-30s, even with sauce and toppings.
Arby’s Fish Sandwich Carbs By Customization
Whether you’re tracking daily macros or just want a lighter lunch, these practical swaps lower carbohydrates while keeping crunch and tang.
Swap The Bun
- No bun, add lettuce wrap: Save ~35 g carbs in one move. Ask for extra lettuce leaves for better grip.
- Open-face option: Keep one bun half and eat with a fork. You’ll cut roughly half the bun’s carbs.
Balance The Sauce
- Light tartar: Request a light spread instead of an extra-saucy build.
- On the side: Dipping lets you control every gram. A little goes a long way with fried fish.
Pick Low-Carb Toppers
- Lettuce, pickles, onions: Flavor and texture with minimal carbohydrates.
- Tomato: Adds brightness and only a gram or two per standard serving.
- Cheese slice: Nearly zero carbs; adds richness that pairs well with a lighter sauce pour.
Estimating Your Exact Carb Count
Menus rotate and builds can vary by location. Use these steps to get a precise number for today’s sandwich:
- Check the current nutrition guide: Start with the base values for the bun and add-ons you plan to use.
- Account for sauces: Add ~2 g carbs per tablespoon of tartar in your calculation.
- Adjust for extras: Tomato slices add ~1–2 g; lettuce and cheese add near zero.
- Watch seasonal builds: A sweeter bun or special spread can raise the total quickly.
Sample Carb Math For Common Orders
These walk-throughs show how quick tweaks change the final number.
Classic Build
Sesame bun (35 g) + breaded fillet + tartar (~2 g) + lettuce → around ~65 g carbs.
No-Bun Version
Fillet + tartar (~2 g) + lettuce → around ~29–30 g carbs. This keeps crunch and tang while cutting a big chunk of carbs.
Extra-Saucy Take
Classic build + 2 extra tablespoons tartar → adds ~4–6 g carbs; expect a total near the high-60s.
Choosing Sides Without Blowing The Budget
Fries push totals up fast. If you want a side, balance your pick with the sandwich style you chose:
- No-bun fish: You’ve saved ~35 g, so a small fry may fit your plan.
- Classic bun build: Consider a non-starchy side or a drink without sugar to stay comfortable on carbs for the meal.
