A McDonald’s medium fry contains about 270 mg of sodium; the exact number can vary with salt and region.
If you’re scanning the menu and wondering about the salt load, you’re not alone. This guide gives you the sodium number for a medium fry, compares sizes, shows how extras change the count, and offers simple ordering swaps. You’ll also see how that sodium stacks up against daily limits from health authorities, so you can make a quick call at the counter.
How Much Sodium Is In A Medium Fry From McDonald’s? Facts, Sizes, And Tips
On current U.S. materials, a medium order lists 320 calories, and the sodium falls around the 270 mg mark per standard serving. Older U.S. nutrition sheets show medium french fries (117 g) at 270 mg sodium, while the current small shows 190 mg sodium on the U.S. site. Canadian data lists a medium at 260 mg sodium for a 110 g serving. That spread reflects portion weight and how much salt lands on the fries after frying. Sources: McDonald’s U.S. product pages and nutrition sheets; McDonald’s Canada nutrition page.
Because restaurants season fries by hand, two medium orders can land slightly differently. Add-ons like ketchup and a salt packet also move the total. The table below pulls together the core items and common extras so you can see everything in one place.
McDonald’s Fries And Add-Ons: Sodium At A Glance
| Item | Standard Serving | Sodium (mg) |
|---|---|---|
| Kids Fry (U.S.) | as listed by size selector | varies by salt; similar per-gram to small |
| Small Fries (U.S.) | one order | 190 mg |
| Medium Fries (U.S.) | ~117 g | 270 mg |
| Large Fries (U.S.) | ~154 g | 350 mg |
| Medium Fries (Canada) | ~110 g | 260 mg |
| Ketchup Packet | 1 packet (10 g) | 110 mg |
| Salt Packet | 1 packet (0.7 g) | 270 mg |
Notes: U.S. small sodium (190 mg) appears on the current McDonald’s U.S. small fries page. The U.S. medium, large, ketchup, and salt packet values come from McDonald’s U.S. nutrition sheets that list standard portions and sodium per item. The Canadian medium sodium (260 mg) is shown on the McDonald’s Canada page for medium fries. Exact sodium can vary with portion weight and how much seasoning sticks to the fries in your restaurant.
If you want the most up-to-date number for your area, use McDonald’s Nutrition Calculator and the medium fries product page for your market. The U.S. small fries page also lists sodium in plain text, which is handy when you’re double-checking a combo.
Sodium In A Medium Fry From McDonald’s — What Changes The Number
Seasoning is the big swing factor. Fries are cooked, then salted. A light shake means less sodium; a heavy shake means more. Freshness matters too: if a batch sits and gets re-salted, sodium creeps up. Region and supplier specs also matter a bit, which is why the Canadian serving shows a slightly different figure than older U.S. sheets.
What About “No Salt” Orders?
Ordering “no salt” reduces surface sodium. You’ll still see a small baseline from the potato and the oil system, but it’s far lower than a salted batch. If you like crunch with less sodium, ask for no salt and add your own pinch, or pair the fries with lower-sodium dips.
How Extras Stack Up
One ketchup packet adds 110 mg. One salt packet adds another 270 mg. A single extra packet flips the math fast: a medium fries at 270 mg plus one salt packet hits 540 mg, and a ketchup packet pushes it to 650 mg. If you’re watching sodium, skip the salt packet and use a dip with little or no sodium.
How That Medium Fry Fits Your Day
The U.S. Food and Drug Administration sets the Daily Value for sodium at 2,300 mg per day for adults. The American Heart Association advises a limit of no more than 2,300 mg, with a better goal of 1,500 mg for many adults. That framing helps translate a single side into the bigger picture of the day’s meals.
Using those benchmarks, the medium order’s 270 mg is just under one-eighth of the 2,300 mg DV. The small’s 190 mg is under one-tenth. The large’s 350 mg is a little over one-seventh. The kicker, though, is the combo: a burger plus fries plus a salty sauce can push you well past half the day’s target in a single sitting.
See the FDA’s page on sodium and the Nutrition Facts label for the Daily Value and label tips. The American Heart Association outlines a simple target on its guide to how much sodium to eat per day.
Real-World %DV For Common Orders
The table below shows percent Daily Value using the 2,300 mg baseline. It’s a quick way to plan a meal without doing math at the table.
%DV Based On 2,300 mg Sodium Target
| Item | Sodium (mg) | %DV (2,300 mg) |
|---|---|---|
| Small Fries (U.S.) | 190 | 8% |
| Medium Fries (U.S.) | 270 | 12% |
| Large Fries (U.S.) | 350 | 15% |
| Medium Fries (Canada) | 260 | 11% |
| 1 Ketchup Packet | 110 | 5% |
| 1 Salt Packet | 270 | 12% |
| Medium + Ketchup | 380 | 17% |
Quick Ways To Trim Sodium And Still Enjoy The Fries
Go Smaller Or Share
If you want the taste but not the full sodium, size down to a small or split a medium. That move keeps the experience and cuts 80–180 mg from the side right away.
Ask For “No Salt”
Ordering no salt drops surface sodium. You’ll get a fresh batch, which helps texture too. If you still want some seasoning, add a tiny pinch from home or use a salt-free spice blend.
Swap The Dip
Ketchup is delicious, but it adds 110 mg per packet. Try a low-sodium ketchup at home, a mustard with minimal sodium, or a simple vinegar-based dip.
Balance The Meal
If the fries are non-negotiable, pick a sandwich or wrap with a lower sodium count and skip extra sauces. Water or unsweetened tea rounds out the tray without adding sodium.
Sourcing, Serving Sizes, And Why Numbers Vary
McDonald’s publishes nutrition numbers by market. The U.S. medium page lists calories, while the detailed nutrient line often lives in the calculator and product nutrition sheets. The Canadian page prints full macro and sodium lines on the product page. That’s why you’ll see 260 mg on Canada’s page and ~270 mg on U.S. materials. Differences also come from serving weight and how much salt adheres after cooking.

- U.S. small fries page for the 190 mg small sodium figure.
- U.S. nutrition sheets that show medium fries at 270 mg sodium, large at 350 mg, ketchup at 110 mg, and a salt packet at 270 mg.
- McDonald’s Canada medium fries page for the 260 mg medium figure.

Answer Recap: Your Medium Fry, In One Line
The core question—how much sodium is in a medium fry from mcdonald’s—lands around 270 mg sodium per order in the U.S., with slight variation across markets and restaurants. If you need an exact number for your location, open the McDonald’s nutrition calculator and check the medium fries entry for that market.
Smart Ordering Cheatsheet
- Want the taste with less sodium? Order a small or share a medium.
- Say “no salt” at the register; add your own small pinch if you like.
- Skip salt packets and keep ketchup to one packet or less.
- Match fries with a lower-sodium main and go easy on sauces.
- Check local numbers in the McDonald’s calculator before you order.
Why This Matters When You Plan The Day
A side that sits at 8–15% of the Daily Value is manageable, especially if you balance the rest of your meals. The trouble starts when a burger, a salty sauce, and two ketchup packets ride along. That combo can blow past half the day’s target in minutes. Keep the fries if they make the meal for you—just trim elsewhere or size down.
