Our Device Size Comparison Tool supports visual 1:1 scale comparison for a wide range of popular gadgets. Compare phones, tablets, laptops, smartwatches, monitors, TVs, and even real-life everyday objects:
Selecting a new smartphone, wearable, or computer display can be challenging when you cannot hold them in your hands. This is why our Device Size Comparison Tool was built: to offer a precise, real-time visual size comparison of your favorite gadgets. Whether you want to perform a quick phone size comparison, check out a detailed smartwatch size comparison, or analyze a display setup, this utility provides accurate dimensions at a glance. By translating raw specifications into interactive digital mockups, we help consumers make informed purchasing decisions based on true ergonomic scale.
A common drawback of standard size utilities is that they only scale devices relative to each other. Our tool solves this by providing a 1:1 scale device comparison. By calibrating the screen with a standard credit card, you can project a real size phone on screen. This lets you visualize the exact physical footprint of any handset right in your browser. It also acts as a screen aspect ratio tool, helping you visualize how different screen dimensions and proportions affect readability and active display areas.
Why is calibration necessary? Every screen has a unique pixel density (PPI). A smartphone displayed on a 4K desktop monitor looks different than on a 1080p laptop because the pixel sizes differ. By placing a physical card on your screen and matching the slider, our software calculates the exact pixels-per-millimeter (px/mm) ratio, achieving perfect physical rendering regardless of your monitor's display settings.
If you are shopping for a flagship handset, comparing dimensions is crucial for ergonomics. For example, doing an iPhone 16 size comparison helps clarify how the base model feels compared to larger iterations. If you're looking at the Android ecosystem, analyzing the new Samsung Galaxy S25 size options allows you to judge pocketability and one-handed reach.
You can do a side-by-side iPhone 16 vs Galaxy S25 size comparison to see how the rivals match up and check the visual smartphone size differences. For even deeper comparisons, you can evaluate:
Beyond simple width and height, you can use our dynamic depth simulator to compare phone thickness and weight. A phone that is only 1mm thicker or 20 grams heavier can cause noticeable hand fatigue over hours of continuous scrolling or calling.
Foldable smartphones present a unique challenge when shopping online because they possess two completely different shapes. For example, when comparing the Galaxy Z Fold 7 or Pixel 9 Pro Fold, they look like standard, somewhat thick phones when folded, but open up to become expansive, square-like tablets. Our tool fully supports Foldable Mode switching. Simply select a foldable device and click the "đą Unfolded" or "đī¸ Folded" buttons that dynamically appear in the control panel to see both states rendered in real time.
Ergonomics aren't just for phones. Wearables have varying sizes that look completely different depending on your wrist width. By checking smartwatch dimensions, you can ensure a watch casing matches your personal profile and doesn't look oversized. Use our dedicated tool for a detailed Apple Watch 10 vs Ultra 2 size comparison to see how the slimmed-down Series 10 compares to the rugged Ultra 2. This makes it simple to analyze smartwatch screen size stats side-by-side.
For desktop workstations, a monitor size comparison is equally valuable. Our canvas functions as a monitor size comparison tool, allowing you to compare displays from standard 24-inch screens all the way up to ultra-wide 49-inch curved monitors. Comparing diagonal measurements alone doesn't convey how much vertical space you lose when shifting from a standard 16:9 monitor to a 32:9 ultra-wide display.
Scroll down to find our interactive phone dimensions chart in mm and full device database to lookup exact dimensions for any mobile device, display, or reference object. Whether you are upgrading your daily carry or redesigning your desk layout, this visual benchmark is the ultimate resource for scale.
This table lists the official width, height, thickness (depth), weight, and screen diagonal measurements for all preloaded reference gadgets and comparison objects.

To compare phone sizes at a true 1:1 scale on your screen, click the "Calibrate (1:1)" button. Place a standard physical credit card, debit card, or ID card against your screen and adjust the calibration slider until the virtual card matches the exact size of your physical card. This determines your screen's precise pixels-per-millimeter (px/mm) ratio, showing all devices in their absolute real-world sizes.
The iPhone 16 Pro Max dimensions are 77.6 mm (width) x 163.0 mm (height) x 8.25 mm (thickness) with a weight of 227 grams. The Samsung Galaxy S25 Ultra dimensions are 77.6 mm (width) x 162.8 mm (height) x 8.2 mm (thickness) with a weight of 219 grams. They are practically identical in width and height, but the Galaxy S25 Ultra is 0.2 mm thinner and 8 grams lighter, offering a slightly lighter in-hand experience.
A phone's screen size (e.g., 6.9 inches or 6.3 inches) is measured diagonally across the active display area. The physical dimensions of the phone (width and height in millimeters) include the body bezels, camera rings, and side frames. Therefore, two phones with the same screen diagonal size can have different physical footprints depending on the thickness of their bezels.
By default, the tool fits the devices proportionally to fit your viewport screen. For absolute accuracy, using the 1:1 Calibration mode ensures millimeter-accurate rendering on any monitor, laptop screen, or tablet.
The screen aspect ratio (such as 19.5:9 on modern iPhones or 20:9 on many Galaxy phones) represents the ratio of the screen's height to its width. A higher aspect ratio means the screen is taller and relatively narrower. This makes the phone easier to hold and use with one hand while maximizing vertical screen space for scrolling social feeds and articles, though it makes the top corners harder to reach.
Generally, smartphones with a physical width under 72 mm (such as the base iPhone 16 or base Galaxy S25) are considered highly ergonomic for single-handed use by average users. Handsets wider than 75 mm (like the iPhone 16 Pro Max or Galaxy S25 Ultra) usually require two-handed operation for typing and reaching the upper edge of the display.
Phone thickness is measured in millimeters (mm) and excludes the camera bump. Even minor thickness increases of 0.5 mm can alter how thick a phone feels in your palm. While thin devices (under 8.0 mm) slip easily into tight pockets, standard protective cases add about 2 to 4 mm of depth and width, which drastically increases the physical dimensions in hand.
Yes, the iPhone 16 Pro Max is physically larger. It measures 163.0 mm (height) x 77.6 mm (width) x 8.25 mm (thickness), whereas the iPhone 15 Pro Max measures 159.9 mm (height) x 76.7 mm (width) x 8.25 mm (thickness). This increase in height and width accommodates a larger 6.9-inch display (up from 6.7 inches) while keeping bezel borders incredibly slim.
Heavy devices (above 220 grams) can cause wrist fatigue during extended usage, regardless of how narrow or thin the phone's profile is. Additionally, weight distribution (how top-heavy the phone is due to large camera lenses) alters the leverage in your hand, changing how secure the device feels when typing one-handed.
Choosing between a 13-inch (like MacBook Air 13 or Dell XPS 13) and a 15-inch (like MacBook Air 15 or Dell XPS 15) laptop depends on your portability needs vs. screen real estate. A 13-inch laptop has a footprint of roughly 290 x 200 mm and is extremely lightweight, fitting into smaller bags. A 15-inch laptop has a footprint of roughly 340 x 230 mm, providing around 25% more screen area for multitasking, side-by-side windows, and media editing, but adds about 300 to 500 grams of weight.
Smartwatch sizes (like 40mm, 42mm, 44mm, 46mm, or 49mm) represent
the height or diameter of the watch casing. Generally:
âĸ Wrists under 150 mm (Thin) fit 38mm to 40mm
models best (e.g. Galaxy Watch 40mm).
âĸ
Wrists from 150 to 180 mm (Medium) look best with
42mm to 45mm watches (e.g. Apple Watch Series 10).
âĸ
Wrists above 180 mm (Large) easily accommodate 46mm
to 49mm models (e.g. Apple Watch Ultra 2). You can use our tool to
compare these watch faces directly against virtual wrist templates
on screen.
Foldable phones have two distinct footprints. For example, the
Galaxy Z Fold 7:
âĸ
Folded mode: Measures 153.5 mm (height) x 68.1 mm
(width) x 12.1 mm (thickness). It is narrow and thick, making it
easy to grip with one hand but bulky in pockets.
âĸ
Unfolded mode: Measures 153.5 mm (height) x 132.6
mm (width) x 5.6 mm (thickness). It becomes a slim, square-like
tablet footprint with a 7.9-inch display, ideal for reading and
multi-window multitasking.
