The answer isn't simple because every microwave is different. But we'll give you the best starting points and teach you the only reliable method to get perfect popcorn every time.
Quick Answer: Microwave Time by Wattage
Here's a general guide based on your microwave's wattage (check the label inside the door):
| Microwave Wattage | Standard Bag (90-100g) | Large Bag (150g+) |
|---|---|---|
| 1200W (high power) | 1:30 - 2:15 | 2:30 - 3:30 |
| 1000W (standard) | 2:00 - 2:45 | 3:00 - 4:00 |
| 800W (medium) | 2:30 - 3:30 | 3:30 - 4:30 |
| 700W (low power) | 3:00 - 4:00 | 4:00 - 5:30 |
Warning: These times are estimates. The difference between perfect popcorn and burnt popcorn can be just 10-15 seconds. Never use the "popcorn button" — it doesn't know your specific bag.
The Real Answer: Listen, Don't Time
Professional popcorn makers and experienced home cooks all agree: the only reliable method is to listen to the popping.
Here's the rule:
Stop when there are 2-3 seconds between pops. At this point, most kernels that can pop have popped. Waiting longer will only burn what's already popped.
Why Timing Alone Doesn't Work
Several factors make timing unreliable:
- Microwave power varies — Even microwaves with the same wattage cook differently based on age, brand, and condition
- Bag position matters — A bag in the center vs. the edge can cook very differently
- Kernel moisture varies — Older popcorn has less moisture and pops faster
- Altitude affects popping — Higher altitudes require longer cook times
- Brand differences — Each brand has different kernel sizes and oil amounts
Step-by-Step: Perfect Microwave Popcorn
- Place the bag correctly — Put it right-side up (check the bag) in the center of the microwave
- Start with a conservative time — Use the lower end of the time range for your wattage
- Listen carefully — Once popping starts, pay attention to the rhythm
- Stop at 2-3 second gaps — When you can count "one-one-thousand, two-one-thousand" between pops, stop immediately
- Open carefully — The bag is full of hot steam. Open away from your face
Common Mistakes to Avoid
- Using the popcorn button — It uses a fixed time that's wrong for most bags
- Walking away — The difference between done and burnt is seconds
- Stopping too early — A few unpopped kernels are normal; don't risk burning for them
- Reusing cooking times blindly — Even the same brand can vary batch to batch

Try It FreePro Tips for Better Popcorn
- Store popcorn properly — Keep bags in a cool, dry place. Old popcorn has less moisture and more duds
- Let the bag rest — Wait 30 seconds after cooking before opening. Some kernels will still pop from residual heat
- Shake the bag — Before opening, give it a good shake to distribute butter/seasoning
- Know your microwave — Once you find the sweet spot for your setup, remember it!
Conclusion
While timing charts give you a starting point, the only truly reliable method is listening for that 2-3 second gap between pops. Your ears are better than any timer — or better yet, let Popcorn Detector do the listening for you!
