We’ve all been there. You open a packet of instant ramen, toss the noodles in a pot, and then stare at the instructions: “Add 500ml of water.”
Wait—how much is 500ml?
Unless you’re the kind of person who keeps a measuring cup by the stove (and kudos to you if you are), this can feel unnecessarily complicated. Especially if you’re cooking for more than one person. Nailing the water-to-noodle ratio is crucial for flavor, but most of us end up just guessing.
So today, we’re solving the ramen water mystery—with everyday items you already have at home.
Whether you’re using a plastic water bottle, a paper cup, or a regular mug, here’s how to get your water measurements just right for a satisfying bowl (or two) of Korean instant noodles.
Why Water Ratio Matters in Ramen
Getting the water amount right is the key to perfect ramen. Too much water and your broth will taste diluted and bland. Too little, and it will be overly salty and concentrated. And when you’re cooking for more than one person, things can get even trickier.
Sure, you could eyeball it—and maybe you’ll get it right by chance. But wouldn’t it be nice to have a reliable method using things from your kitchen?
Let’s break it down.
Method 1: Use a 500ml Water Bottle
If you’ve got a standard plastic water bottle (like Dasani, Poland Spring, or Kirkland), you’re in luck. These bottles are typically 500ml, which is the exact amount recommended for one serving of ramen.
Here’s how that works:
- 1 serving = 500ml = 1 full bottle
- 2 servings = 1000ml (1L) = 2 bottles
This is probably the easiest and cleanest way to measure, especially if you’re camping, living in a dorm, or just want no-fuss cooking.
If you’re making specific types of Korean ramen, here are a few brand-specific suggestions:
- Paldo Namja Ramen or Kimchi Ramen: 500ml = 1 bottle
- Paldo Ilpoom Seafood Ramen: 550ml = 1 bottle + about ⅓ paper cup
- Paldo Ilpoom Jjajangmen: 600ml = 1 bottle + about ½ paper cup

Method 2: Use a Regular Paper Cup
A standard paper cup (like the ones at parties or coffee stations) usually holds about 180ml of water. It’s not exact science, but it’s close enough for ramen.
Using paper cups, the measurements look like this:
- 500ml = 2 full cups + a little more (½ cup)
- 550ml = 3 full cups + a splash
- 600ml = 3 full cups + about ⅓ to ½ more
This method is super convenient, especially if you don’t have bottles around. Plus, the cup is small enough to adjust amounts easily, which is handy if you’re the kind of cook who likes to “taste and adjust.”
Just one thing to keep in mind: disposable cups aren’t the most eco-friendly. If you can, try using reusable ones for measuring!
Method 3: Use a Mug from Your Kitchen
Almost everyone has a classic 10 oz (about 300–350ml) mug in their kitchen—maybe even one you got as a gift or free at a conference. These mugs are great for quick measurements.
Most standard mugs hold around 350ml, though some smaller mugs are closer to 250ml, and oversized mugs can go up to 450ml. Here’s a general guide using a 350ml mug:
- 500ml = 1 full mug + ⅘ of a paper cup
- 550ml = 1 full mug + about ¾ of a paper cup
- 600ml = 1 full mug + about a full paper cup
The best thing about using mugs is that you can start to memorize the amount over time. Eventually, you won’t even need to think about it—you’ll just know how full your mug should be for that perfect bowl of noodles.
Bonus Tip: Check the Instructions (But Don’t Rely on Them Blindly)
Sometimes ramen packages simply say “2 cups” or “3 cups,” but they rarely specify what size cup they mean. Usually, they’re referring to Korean paper cup standards (about 180ml), but it’s not always consistent.
That’s why having your own reference system—whether it’s a bottle, cup, or mug—is a smart move.
Final Thoughts: Make Ramen the Way You Like It
At the end of the day, ramen isn’t about perfect science—it’s about comfort, warmth, and flavor. If you like your broth stronger, use a little less water. If you like it lighter and milder, go a bit over. These methods are just starting points to help you get it right consistently.
Whether you’re cooking for one, sharing a midnight snack with a friend, or impressing someone with your ramen-cooking skills, knowing how to measure water properly will take your noodle game to the next level.
Now go forth and cook! Your perfectly balanced bowl of ramen awaits.
