What is upload speed and why does it matter?
When choosing an internet service provider, most ads highlight download speed. However, upload speed (upload speed) is just as crucial to your internet experience – just in different ways.
Simply put, upload speed it is the amount of data your computer or phone can send to the internet per second. Download speed, on the other hand, measures how much data you receive.
- Download = when you watch (YouTube, Netflix, browsing)
- Upload = when you send (photo upload, email attachment, Zoom call, file sharing)
Upload speed is measured in megabits per second (Mbps). The higher this number, the faster your files and data reach their destination.
Why is upload speed important?
If you only read news and occasionally watch a video, you might not miss high upload speed. But if you work from home, stream, play online games or upload content (YouTube, Instagram), then a weak upload will be immediately noticeable:
- Video calls stutter, the image „freezes”
- File uploads take minutes (large photos, videos, presentations)
- In online games you experience lag
- Cloud sync (Google Drive, iCloud, OneDrive) becomes slow
- Live streaming quality deteriorates

What are different upload speeds sufficient for?
Many people don't know how much upload is needed for various activities. The table below helps you navigate:
| Upload speed | What is it sufficient for? | Recommended for whom? |
|---|---|---|
| 1-5 Mbps | Basic email, chat (Messenger, WhatsApp), light browsing, Google Docs editing | Elderly family member, infrequent internet user |
| 5-10 Mbps | HD video call (Zoom, Teams, Google Meet), photo uploads, simple cloud sync | Home user, occasional home office |
| 10-25 Mbps | Full HD video call, large file uploads, 1080p live streaming, online gaming | Home office worker, regular content sharer |
| 25-50 Mbps | 4K live stream, large team video call, uploading to YouTube, multiple devices simultaneously | Content creator, large family, software developer |
| 50-100 Mbps+ | Professional content creation, 4K/HDR stream, large files in seconds, server operation | Business, professional streamer, graphic designer/studio |
Highlight: For most Hungarian households, 10-25 Mbps upload is sufficient for everyday use. More is only needed if you use the internet at a professional level.
How to measure your upload speed?
The easiest way is to run a internet speed test. speedtest365.hu is designed for exactly this.
Steps:
- Open the speedtest365.hu page
- Click the Start measurement button
- The test automatically measures both download and and upload speed
- The result appears within seconds
During the test, the server sends a small data packet to your device (download), then your device sends another packet back to the server (upload). The measurement reveals your actual upload speed.
What to consider before measuring?
- Turn off all downloads, streams, and background updates — they distort the result
- Preferably connect via Ethernet cable, not over WiFi
- Perform 3-5 measurements at different times of day — providers may be slower in the evenings
- If the result is significantly lower than what is stated in your contract, it may be worth filing a complaint with your provider

What affects upload speed?
Several factors determine the actual upload speed you achieve.
WiFi vs. Ethernet
Wireless connection is convenient, but often WiFi is the bottleneck. Older routers (802.11n, 802.11ac) cannot fully utilize modern, fast internet packages. Ethernet cable provides a more stable and faster connection — and upload speed is less affected by interference.
Router settings
A poorly configured router can also cause issues:
- QoS (Quality of Service) settings: if upload traffic is not prioritized, upload speed may slow down
- Router firmware: outdated software = weaker performance
- Overloaded WiFi channel: neighboring routers can also interfere with the signal
Provider and technology
The technology used by your provider fundamentally determines the upload speed you can expect:
- FTTH (fiber): Symmetrical connection offers equal download and upload speeds
- Cable (DOCSIS): Download is typically much faster than upload (up to a 10:1 ratio)
- ADSL/VDSL: With older copper-based connections, upload speed is usually very low
Age of network devices
Routers, switches, and network cards older than 3-4 years are not always able to keep up with today's speeds. If you often experience slow uploads, it may be worth replacing your router with a more modern one.

How to Increase Upload Speed? (Practical Tips)
Before switching to a more expensive subscription, try these:
- Switch to Ethernet — the simplest and cheapest solution. A 10-meter cable costs a few thousand forints and can make a huge difference.
- Update your router's firmware — manufacturers often release performance-improving updates that many people miss.
- Turn off unnecessary background sync — Google Drive, OneDrive, iCloud, and other cloud services sync in the background, constantly loading your upload bandwidth.
- Switch to a more modern router — a WiFi 6 (802.11ax) router provides better bandwidth management, especially with multiple devices.
- Fix your WiFi signal — if you must stay on WiFi, place the router in a central location, away from the microwave and other electronic devices.
- Check your provider's actual network load — during evening peak hours, the connection slows down for all providers. If this is extreme, it may be worth choosing another provider.

Upload Speed Requirements by Activity
It matters what you use the internet for. The breakdown below helps you choose the right package.
Home office
The foundation of remote work is a stable video call and file sharing. A Zoom or Teams call in HD quality requires 2-4 Mbps upload. If you work a lot in the cloud (SharePoint, Google Workspace), expect daily file uploads as well.
Recommended: minimum 10 Mbps upload
Video calls and online meetings
Most platforms (Zoom, Google Meet, Microsoft Teams) recommend 3-5 Mbps for HD. If you're in a 4-5 person meeting and someone shares their screen, that also consumes upload bandwidth.
Recommended: 5-15 Mbps upload (with family members, multiple calls at once)
Online gaming
Many think gaming requires fast download — in reality, ping (latency) and upload speed are more important. Games send relatively little data (10-50 Mbps is plenty), but stability is critical.
Recommended: 5-20 Mbps upload with low ping
Content creation and streaming
If you upload videos to YouTube, stream on Twitch, or share high-resolution photos, you need serious upload speed here.
- 1080p live stream: 6-8 Mbps
- 4K live stream: 25-35 Mbps
- Large video upload (4K, 30 minutes): At 50 Mbps, about 10-15 minutes
Recommended: 25-50 Mbps upload (or more)
Multi-device household
In a modern household, 3-5 devices may use the internet simultaneously. If one child is on Zoom, another parent is streaming, and a third device is syncing, upload speed quickly runs out.
Recommended: 20-50 Mbps upload for family use
Comparison of Hungarian Providers' Upload Speeds
The table below shows the typical upload speeds of major Hungarian internet providers in the most common packages. The data is for informational purposes — always check the current offer.
| Provider | Technology | Typical upload (Mbps) | Note |
|---|---|---|---|
| Telekom | FTTH | 100-1000 | Symmetrical fiber — same upload as download |
| Telekom | VDSL | 10-30 | Technological limitation: lower upload |
| Digi | FTTH | 100-500 | Symmetrical: excellent value for money |
| Vodafone | Cable (DOCSIS 3.1) | 20-50 | Upload lower than download |
| Yettel | 5G FWA | 10-50 | Depends on signal strength and tower load |
| PR-Telecom / UPC successor | Cable | 15-40 | Variable: differs by area and package |
Key takeaway: If upload speed matters, choose fiber (FTTH) service where the provider offers symmetrical upload. With cable, always expect upload to be significantly slower than download.
Frequently Asked Questions about upload speed (FAQ)
What is a normal upload speed in Hungary?
The average upload speed in Hungary in 2026 ranges around 20-50 Mbps, but this depends heavily on the technology. With fiber connections, much higher values are achievable.
How much upload speed do I need for Netflix?
Netflix streaming primarily requires download speed. Upload only matters if the Netflix app sends back quality signals or if other devices are also loading the network.
Why is upload slower than download?
This stems from the nature of the technology. Home internet was originally designed for downloading more than uploading. In cable (DOCSIS) networks, bandwidth is asymmetric: most of the bandwidth is reserved for download. Fiber (FTTH) connections solve this, where the two directions can be fully symmetrical.
Will a new router help with upload speed?
Yes, especially if your current router is 3-4 years old or uses an older WiFi standard (e.g., 802.11n). A modern WiFi 6 router handles parallel connections better and provides greater bandwidth.
What should I do if I get the upload promised by my provider, but it's not enough?
In this case, there's no other solution than upgrading to a higher-tier package, or switching to another provider, that offers better upload speeds. Fiber (FTTH) service is usually the best choice.
Summary
Upload speed is not only important for content creators — it has become part of home office, online education, and everyday digital life. Today, even an average user should aim for 10-20 Mbps upload speed, while professional users should aim for above 50 Mbps.
