Internet Speed Requirements for Longmont Households
The speed you need in Longmont depends on how many people and devices use your connection simultaneously. A single person streaming video and browsing the web can get by with 50-100 Mbps. A household of 2-3 people with regular streaming and video calls should target 200-300 Mbps. Larger families with 4 or more heavy users benefit from 500 Mbps to 1 Gbps plans, especially when multiple people are streaming in 4K, gaming online, or working from home at the same time.
Upload speed matters just as much as download speed for Longmont residents who work remotely. Video conferencing platforms like Zoom and Teams require at least 5 Mbps upload for stable HD video, and 10 Mbps or more for group calls with screen sharing. If multiple household members participate in video calls simultaneously, ensure your plan provides at least 20-25 Mbps upload speed. Fiber plans offer the best upload performance with symmetrical speeds.
