Phone Sized can show devices at true physical scale, but only after you calibrate the page with a real-world object. The site provides a credit card image for this purpose: you enlarge that image on your screen until it matches the size of an actual credit card you hold against it, and the site then rescales every device image so they appear at real-life size. This works on any screen, but the calibration is per-screen and per-zoom-level, so you need to redo it if you change browser zoom, rotate your device, or move to a different monitor.

Why calibration is needed

A browser has no way of knowing how large your screen's pixels physically are. The same 400-pixel-wide image is a different physical size on a phone, a laptop, and a 27-inch monitor. Phone Sized solves this by letting you anchor the scale to an object with a fixed, known size — a standard credit card (85.60 mm × 53.98 mm, or 3.370 in × 2.125 in). Once the on-screen card matches your physical card, the pixel-to-millimeter ratio is known, and every other image can be scaled correctly.

Step-by-step

1. Open the comparison page on phonesized.com and add the devices you want to view.
2. Find the credit card image option and place it on the comparison area.
3. Hold a real credit card flat against your screen, lining up one edge with the on-screen card.
4. Enlarge or shrink the on-screen card image until its edges match your physical card exactly. Use the browser zoom or the site's resize control, whichever the page exposes.
5. Once matched, leave the zoom level untouched. The device images are now displayed at real-life size.
6. Compare the phones or tablets on screen against each other, or hold your own device next to the screen to see the difference directly.

Expected result: the device outlines on screen correspond to the actual physical dimensions of those devices, so a phone that is 6 mm taller than another will look 6 mm taller on your screen.

What you can do once calibrated

• Side-by-side mode — view two devices next to each other and observe the size difference directly.
• Stacked mode — see one device layered on top of another, which makes width and height differences easier to judge.
• Outline-only view — show just the device outlines, which is especially useful in stacked mode where solid images would hide the device underneath.
• Dimension readout — the site reports the difference in mm, inches, and percentage. The select buttons for this sit below each device, and you can compare two devices at a time.

Common snags

• Calibration drifts after zooming. Any change to browser zoom invalidates the match. Recalibrate before trusting the sizes.
• Only two devices at once. The dimension-difference feature is limited to a two-device comparison, so for a three-way decision you need to run it in pairs.
• Screen size limits usefulness. On a small phone screen, two large tablets won't fit at true scale at the same time. Use a desktop monitor for tablet comparisons.
• Credit card must be a real one. A printed or on-screen reference won't work, since the whole point is matching against a physical object with known dimensions.

When this is worth doing

Calibration is worth the extra step when the exact physical feel matters — for example, deciding whether a 6.8-inch phone will actually fit your hand or pocket compared with your current 6.1-inch model, or checking whether a tablet will fit a bag sleeve. If you only need a rough sense of which device is bigger, the uncalibrated side-by-side view is faster and good enough.

Phone Sized also maintains a broad device database covering Apple, Samsung, Huawei, Xiaomi, Oppo, OnePlus, Sony, Nokia, ZTE, and others, and adds newly announced devices regularly. If a device you want is missing, the site's author asks that you contact him on Twitter to request an addition.

Phone Sized displays each device's dimensions in millimeters, inches, and percentage difference once you select two devices for comparison. The site is a visual phone size comparison tool that also includes tablets in its database, and its stated purpose is to let you see how different devices differ in size relative to each other. The size data appears as text alongside the visual comparison, so you get both a picture and numbers.

What you can see for a single device

When you open a device in the comparison page, the site presents it visually. The page evidence describes the tool as a way to "view how different device differ in size compared to other mobile devices" and to "see the real size of your device." The real-size view works through a calibration option: you can add a credit card image and enlarge it to match your actual credit card, and the site then resizes the other images so they are presented at real-life size.

That means the size information for one device is primarily visual and scale-based rather than a spec sheet. The site does not describe showing weight, thickness in isolation, or screen-to-body ratio as separate data points.

What you see when comparing two devices

The comparison is where the numeric size data appears. According to the site, the latest feature added "allows you to see the dimension difference in mm, inches and percentage." The select buttons for this are located below each mobile device.

Two limits apply:

• You can only compare two devices at a time.
• Once you choose the second smartphone or tablet, the textual comparison appears.

So the size information is not a static table on each device page — it is generated dynamically from your two selections. If you want numbers, you need to pick both devices first.

The two comparison modes and how they present size

The outline option is specifically described as making it "easier to compare the devices when they are stacked up," because solid images overlap and hide the edges underneath.

How to get the size numbers

1. Open the comparison page and select your first device.
2. Select the second device using the select button below it.
3. Read the textual dimension difference that appears — it is given in mm, inches, and percentage.
4. Switch between side-by-side and stacked modes to see the same pair visually.
5. If you want real-life scale, add the credit card image and resize it to match a physical card.

The expected result is a visual overlay plus a numeric difference, so you can judge both "how much bigger" and "how it looks."

What the database covers

The device list includes phones and tablets from Apple, Samsung, HTC, Huawei, Asus, Amazon, Acer, Microsoft, LG, Meizu, Xiaomi, Vodafone, ZTE, Sony, Nokia, OnePlus, Oppo, and others. Newly announced devices are added on a regular basis, and the site lists recently added devices with dates. If a device is missing, the site says you can contact the creator on Twitter to request it.

Common points to watch

• The site is labeled beta, so behavior and coverage may change.
• Only two devices can be compared at once, so a three-way comparison requires two separate passes.
• The percentage figure is a difference between the two selected devices, not a standalone spec — it changes with your selection.
• Real-life size depends on calibrating the credit card image correctly; if that step is skipped, the on-screen sizes are not to scale.
• The site does not state pricing or login requirements in the available material, so treat access details as unconfirmed rather than assuming it is free or account-free.

Phone Sized (phonesized.com) is a free visual phone size comparison tool. You pick two mobile devices from its database and view them side by side or stacked on top of each other to see how their physical dimensions differ. It covers phones and tablets, and it's useful if you want to judge whether a new device will feel bigger or smaller than the one you already own — or see a device at its real-life size on your screen.

What you can do on the site

The core action is comparing two devices. You can only compare two at a time, so the tool is built around one-to-one comparisons rather than large group views.

Two main comparison modes are available:

• Side by side — the two devices appear next to each other, making width and height differences easy to see.
• Stacked — one device sits on top of the other, which helps when you want to compare overall footprint or how much taller one phone is.

There's also an outline-only view, which strips the devices down to their outlines. This is especially handy in stacked mode, where solid device images would hide the one underneath.

See a device at its real size

The site includes an option to add a credit card image and enlarge it until it matches a physical credit card you hold against your screen. Once matched, the other device images are resized proportionally, so they're presented at their real-life size. This is the practical way to answer "will this phone actually fit my hand or pocket?" rather than just reading a spec sheet.

Read the dimension differences

A later feature shows the dimension difference between the two selected devices in millimeters, inches, and percentage. The select buttons for this sit below each mobile device. This turns a visual comparison into concrete numbers — useful when two phones look nearly identical on screen but differ by a few millimeters.

Which devices are covered

The database is extensive and spans phones and tablets from many manufacturers, including Apple, Samsung, HTC, Huawei, Asus, Amazon, Acer, Microsoft, LG, Meizu, Xiaomi, Vodafone, ZTE, Sony, Nokia, OnePlus, and Oppo, among others.

Newly announced devices are added regularly. The site lists recently added devices on the page — for example, entries such as the Honor X9e Pro, Xiaomi 18 Pro Max, Oppo Find X10 series, and Vivo X500 Pro Max appear with their addition dates. If a device you want isn't listed, the site's stated approach is to contact the creator on Twitter to request it.

Other things worth knowing

• Language support: the interface can be switched among many languages, including Spanish, German, Italian, French, Russian, Korean, Japanese, Portuguese, Arabic, Chinese, Turkish, Hindi, Hebrew, Swedish, Thai, and Indonesian.
• Notch comparison: there's a dedicated option to compare notches between devices.
• Status: the site is labeled as beta, so expect the feature set to keep evolving.

When to use it

Phone Sized is most useful when a spec sheet isn't enough — when you want to see whether a phone is noticeably wider than your current one, whether a tablet dwarfs a phone you own, or whether a device's real-world size matches your expectations. If you only need raw dimensions, a spec table works; if you need to see the difference, this tool is the point.

Phone Sized lists phones and tablets from Apple, Samsung, HTC, Huawei, Asus, Amazon, Acer, Microsoft, LG, Meizu, Xiaomi, Vodafone, ZTE, Sony, Nokia, OnePlus, Oppo, and others, according to the site's own description. The database covers both mobile phones and tablets, and the homepage shows a "Newly Added Mobile Devices" list so you can check whether a recent model has already been added.

Brands confirmed on the site

The site names the following manufacturers among the companies represented in its device list:

• Apple
• Samsung
• HTC
• Huawei
• Asus
• Amazon
• Acer
• Microsoft
• LG
• Meizu
• Xiaomi
• Vodafone
• ZTE
• Sony
• Nokia
• OnePlus
• Oppo

Samsung appears twice in the site's own wording, so treat the list above as the set of distinct names it mentions rather than a ranked or complete index.

Phones and tablets are both included

Despite the name, Phone Sized also lists tablets. The stated purpose is to let you see how different devices differ in size from other mobile devices, so a phone and a tablet can be placed in the same comparison.

Checking whether a specific model is listed

The homepage surfaces recently added devices with their names and dates. Examples visible on the page include:

Clicking one of these entries opens it in the comparison page. This list is the fastest way to confirm coverage of a newly announced device, since the site says new devices are added on a regular basis.

If your device isn't listed

The site states that if you find a device that isn't listed and want it added, you can contact the operator on Twitter and they will do their best to add it as soon as possible. There is no separate submission form described on the page — Twitter is the stated channel.

Practical notes

• The site is labeled beta, so the device list and features may change.
• Comparison is limited to two devices at a time; once you pick the second phone or tablet, the textual comparison appears.
• The interface is available in many languages, including Spanish, German, Italian, French, Russian, Korean, Japanese, Portuguese, Arabic, Chinese, Turkish, Hindi, Hebrew, Swedish, Thai, and Indonesian.

Phone Sized is a visual size comparison tool for phones and tablets. To compare two devices, open the comparison page, select your first device, then select your second device — the site supports only two devices at a time. You can then switch between side-by-side and stacked views, and use the outline option to make stacked comparisons easier to read.

Step-by-step: comparing two devices

1. Open the comparison page. The site's main heading is "Mobile Phone Size Comparison," with a "Start Comparing!" entry point.
2. Pick your first device. Use the device list or search to select the first phone or tablet.
3. Pick your second device. Once you choose the second smartphone or tablet, the textual comparison appears. Note that you can only compare two devices at once.
4. Choose a view mode. Switch between side-by-side and stacked depending on what you want to see.
5. Read the dimension difference. The latest feature shows the difference in mm, inches, and percentage. The select buttons for this are located below each mobile device.

Side-by-side vs. stacked: which view to use

If your main question is "which one is wider," side-by-side is usually faster. If you care about height or how the top and bottom edges align, stacked with outlines is easier to read.

Seeing devices at real-life size

Phone Sized includes an option to add a credit card image, which you can enlarge to match your actual credit card. The site then resizes the other images so they are presented at real-life size. This is useful when you want to judge how a device would feel in hand rather than just how it compares to another device.

Device coverage and keeping the list current

The database covers phones and tablets from many brands, including Apple, Samsung, HTC, Huawei, Asus, Amazon, Acer, Microsoft, LG, Meizu, Xiaomi, Vodafone, ZTE, Sony, Nokia, OnePlus, and Oppo, among others. Newly announced devices are added on a regular basis — the site lists recently added devices with dates, and you can click any of them to open it in the comparison page. If a device you want isn't listed, the site says you can contact the creator on Twitter to request it.

Practical notes

• The site is labeled beta, so expect the interface and device list to keep changing.
• The interface supports many languages, including Spanish, German, Italian, French, Russian, Korean, Japanese, Portuguese, Arabic, Chinese, Turkish, Hindi, Hebrew, Swedish, Thai, and Indonesian.
• Only two devices can be compared at once, so for a three-way decision you'll need to run more than one comparison.
