TV planning tool
TV Size Calculator: Match Screen Size to Viewing Distance
Use your seating distance and room habits to estimate a comfortable TV size range. This is a planning estimate—not a lab certification or THX rule.
This tool is a planning estimate, not a product rating, price quote, medical/legal/safety certification, or retailer availability check. Based on your inputs only—no live price, stock, or availability verification.
How this estimate works
The calculator converts viewing distance into safe and immersive diagonal ranges, then snaps results to common TV sizes (43″ through 98″). Bright rooms and low-quality sources nudge recommendations smaller; gaming and movies may stretch the upper band slightly. Optional wall width helps flag when a screen may exceed furniture limits.
Your result will appear here after you submit the form.
What to check next
- Measure seating distance at eye level, not rug edge to wall
- Check stand feet width—not just screen diagonal
- Compare panel type on the OLED vs Mini LED matcher before you shortlist models
Common mistakes
- Buying the biggest sale size without checking cable or stream quality at that scale
- Ignoring stand width on narrow media consoles
