The largest screens on US-market cell phones currently measure up to 6.9 inches diagonally, with a few models reaching 7.0 inches. These are found in the ultra-large category often called phablets. Screen size alone isn’t everything—consider bezels, aspect ratio, and one-handed usability.

When asking “what cell phones have the biggest screens,” the answer starts with diagonal measurement. In the US market, a screen is generally considered “big” at 6.5 inches or larger. However, the usable area also depends on aspect ratio (e.g., 19.5:9 vs. 20:9) and bezel size. A phone with a 6.7-inch display and slim bezels may have a smaller footprint than an older 6.4-inch model with thick borders. Most major carriers now offer at least one model near the 6.9-inch mark, often marketed as an “ultra” or “plus” variant.
Current Largest Screen Sizes
As of early 2026, the largest screens widely available in the US are 6.9 inches on several premium-tier models from the leading manufacturers. A handful of niche devices (often from brands focused on media consumption) reach 7.0 inches, but these are less common. Below is a comparison of typical screen-size categories you’ll find at major retailers and carriers:
| Category | Diagonal Range | Typical Use |
|---|---|---|
| Compact | 5.4–6.0 in | One-handed, pocket-friendly |
| Standard | 6.1–6.4 in | Balanced everyday use |
| Large | 6.5–6.7 in | Media, productivity |
| Ultra-Large (Phablet) | 6.8–7.0 in | Gaming, dual-window multitasking |
According to industry data from Display Supply Chain Consultants (DSCC), the share of smartphones with screens 6.8 inches or larger exceeded 18% of US sales in Q4 2025, up from 12% the prior year.
Trade-Offs of Large Screens
A bigger screen provides more immersive video, easier reading, and better split-screen multitasking. However, it comes with downsides:
- Portability: Phones above 6.8 inches often require two-handed use and may not fit in standard pockets.
- Weight: Ultra-large models typically weigh over 220 grams, causing hand fatigue during long sessions.
- One-Handed Operation: Reaching the top of the screen becomes difficult; many users rely on software one-handed modes.
- Price: The largest screens are almost always paired with premium processors and cameras, pushing the retail price above $1,000.
How to Choose the Right Size
Consider your primary activities:
- Media consumption — If you watch movies or play games frequently, aim for 6.7 inches or larger.
- Productivity — For reading documents or using multiple apps, 6.5+ inches with a high aspect ratio helps.
- Portability — If you carry your phone in a front pocket or use it one-handed often, 6.4 inches or smaller may be better.
- Budget — Large-screen phones are available from budget providers at under $400, but expect trade-offs in camera quality and refresh rate.
Screen Size Trends
The trend toward larger screens continues, but the pace has slowed. The average US smartphone screen size has stabilized around 6.4 inches in 2026, according to the Consumer Technology Association (CTA). Foldable smartphones are beginning to blur the line between phone and tablet; when unfolded, some offer screens of 7.6 inches or more, though they are not yet considered mainstream. For now, the largest rigid-screen phones remain the most direct answer to “what cell phones have the biggest screens.”
