Convert px to pt free online with DPI control. Learn the exact formula, 96 vs 300 DPI tables, and a worked print example.

A px to pt converter turns a screen measurement in pixels into a print measurement in points, using the formula pt = px × 72 ÷ DPI. At the web standard of 96 DPI, 16 px equals 12 pt, 24 px equals 18 pt, and 100 px equals 75 pt. The conversion only stays accurate when you know the DPI, because the same pixel count means a different point size at 72, 96, 150, or 300 DPI.

This matters most when a design leaves the screen. A heading that looks perfect in a browser can print far too small or far too large if its pixel size is carried into a print file unchanged. The fix is not guesswork. It is one formula, the right DPI, and a quick check before you send the file to print.

Why does px to pt conversion go wrong so often?

Px to pt conversion goes wrong because pixels and points measure different things. A pixel is a screen unit tied to display resolution, while a point is a physical print unit where 72 pt always equals one inch. Treating them as interchangeable ignores DPI, and that single omission is what makes printed text come out the wrong size.

For example, 16 px body text reused in a 300 DPI brochure becomes just 3.84 pt — far too small to read — even though nothing in the design changed except the medium.

The reverse mistake is just as common. A print designer hands a developer a 12 pt specification, and the developer types 12 px into CSS. At 96 DPI, 12 pt is actually 16 px, so the live site renders smaller than the approved print proof. Both errors come from the same habit: copying a number across mediums without converting it.

How do you convert px to pt?

To convert px to pt, multiply the pixel value by 72 and divide by the DPI: pt = px × 72 ÷ DPI. At 96 DPI this simplifies to px × 0.75, so 16 px becomes 12 pt and 48 px becomes 36 pt. At 300 DPI the same formula gives a much smaller point size, because each pixel represents a smaller physical dot.

The 72 in the formula is not arbitrary. There are 72 points in one inch, and DPI tells you how many pixels fit into that same inch. Dividing by DPI therefore translates a pixel count into inches first, and multiplying by 72 turns those inches into points. Once you see that chain — pixels to inches to points — the formula stops feeling like magic and starts feeling like bookkeeping.

For the reverse direction, flip it: px = pt × DPI ÷ 72. At 96 DPI, multiply points by 1.3333. So 12 pt becomes 16 px, and 72 pt becomes 96 px. The free Px to Pt converter handles the px-to-pt direction, and it also shows the cm, mm, and inch equivalents for the same value, which helps when a print shop asks for dimensions in centimetres rather than points.

A worked example: from a web heading to a print flyer

Here is one complete conversion, with real inputs and real outputs, so you can check your own work against it.

The scenario. Amna, a freelance designer in Lahore, is preparing a one-page flyer for a local bakery. The bakery's website uses a 32 px heading, and Amna wants the flyer heading to match. The flyer will be printed at 300 DPI. Her first instinct is to set the heading to 32 pt in the print file — but that would be wrong.

Step 1 — enter the pixel value. Amna opens the Px to Pt tool and enters 32 in the pixel field.

Step 2 — choose the DPI. She selects 300 DPI, because that is the print resolution, not the 96 DPI web default.

Step 3 — read the result. The tool returns 7.68 pt, plus the inch, cm, and mm equivalents. Amna immediately sees the problem: a 7.68 pt heading on a flyer would be barely readable.

Step 4 — work backwards to a usable size. Instead of forcing the web size into print, Amna decides the flyer heading should be 28 pt. Reversing the formula (px = 28 × 300 ÷ 72) gives 116.67 px — proof that print and screen sizes are simply not the same scale. She sets the flyer heading to 28 pt, keeps the website heading at 32 px, and both now look right in their own medium.

The lesson is practical, not theoretical. Conversion does not mean copying a number. It means translating a visual size from one medium's rules to another's, and checking the result before it reaches the printer.

Px to pt at the DPI values you will actually use

The table below shows common pixel sizes at the two DPI values most people meet: 96 DPI for screen work and 300 DPI for print work. Use it as a sanity check, then confirm your exact value in the tool.

Notice how quickly the 300 DPI column shrinks. That is why print files built from pixel numbers without conversion so often arrive with microscopic text — the designer did nothing wrong except skip one division.

Using the free Px to Pt tool, step by step

Enter any non-negative pixel value, pick 72, 96, 150, or 300 DPI, read the point result plus its inch, cm, and mm equivalents, check the quick reference table, and copy the result with one click. There is no account and no upload. If you need the opposite direction, use the PT to PX converter linked from the tool page, or the companion px to cm guide and px to mm guide.

What DPI should you actually choose?

Choose by output: 72 DPI is the classic print reference (1 px = 1 pt), 96 DPI is the CSS web standard, 150 DPI suits large-format work viewed from a distance, and 300 DPI is the standard for sharp commercial print. When in doubt, ask the printer before converting — a two-minute question saves a reprint.

Five mistakes that break a px to pt conversion

The most common errors are assuming 1 px equals 1 pt at any DPI, using the screen DPI for a print file, rounding too early in a chain of conversions, and mixing CSS pixels with device pixels. Each one is easy to spot once you check the DPI first.

What this converter does not do — honest limits

A converter is a calculator, not a design tool, and it is worth stating its limits plainly. It converts one direction only, px to pt; for pt to px you need the reverse tool. It does not adjust for font rendering, line height, or how a particular typeface looks at a given size — a 12 pt font in one typeface can look larger than 12 pt in another. It also does not fix a low-resolution image: converting the text size will not make a blurry 72 DPI logo sharp at 300 DPI. For that, you need a higher-resolution source file, not a different number.

A concrete CodexFuse workflow for designers and small studios

Conversion tools solve one step, but designers lose more time to the setup around the work: a portfolio site that goes down before a client pitch, email that lands in spam, and backups nobody remembers to run. CodexFuse addresses that surrounding work as one managed platform on credits, and the workflow below is specific enough to follow.

• Host the portfolio on credits: move the portfolio or studio site to CodexFuse hosting and pay with credits as you use resources, instead of a fixed monthly subscription that charges the same in a quiet month as a busy one.
• Put client email on the same platform: set up business email on your own domain through CodexFuse, so proposals and print approvals come from a professional address rather than a free mailbox that clients may distrust.
• Let backups run themselves: enable managed backups for the site and its files, so a broken update or an overwritten design asset is recoverable without rebuilding from scratch.
• Check the site before the pitch: before sending a client link, confirm the site loads and the contact form works — the same kind of pre-flight check as verifying a print size before sending it to the printer.

Frequently Asked Questions

How do I convert px to pt?

Multiply the pixels by 72 and divide by the DPI. At 96 DPI, multiply by 0.75: 16 px is 12 pt, 24 px is 18 pt, and 100 px is 75 pt. Enter the pixel value and DPI in the Px to Pt converter and it does the division for you.

What is 16 px in pt?

At 96 DPI, 16 px is 12 pt. At 72 DPI it is 16 pt, at 150 DPI it is 7.68 pt, and at 300 DPI it is 3.84 pt. The answer always depends on DPI, which is why the tool asks for it.

Why is 1 px equal to 0.75 pt?

Because 1 px is defined as 1/96 of an inch in CSS and 1 pt is 1/72 of an inch, so 1 px equals 72 ÷ 96 = 0.75 pt. This is a definition, not a measurement of any particular screen.

What DPI should I use for print?

Use 300 DPI for sharp commercial print such as flyers and brochures. Use 96 DPI for web work, and confirm with your printer if they specify a different document resolution.

Can I convert pt back to px?

Yes, with the reverse formula px = pt × DPI ÷ 72. At 96 DPI, 12 pt becomes 16 px and 72 pt becomes 96 px. Use the PT to PX converter linked from the Px to Pt tool page for that direction.

Does the converter work for decimals?

Yes. You can enter any non-negative number, including decimals. Results show up to four decimals below 1 and two decimals otherwise, and negative numbers are rejected.

Convert it once, check it twice, then print with confidence

Px to pt conversion is a small step, but it sits between your design and a finished product a client will hold in their hands. Get the DPI right, run the formula or the free tool, and check the result against the table above before you export. That one-minute habit is the difference between a flyer that looks intentional and one that comes back from the printer needing a reprint.

If you run a design studio, a print shop, or a small business that produces both web and print work, move the surrounding setup to CodexFuse today: host your portfolio, run business email on your own domain, and keep managed backups running — all fully managed, all on credits, with no subscription lock-in. Start with the free Px to Pt converter for today's conversion, then get started with CodexFuse and put the rest of your IT on the same managed platform.
