# Pixels to Inches Calculator

Convert pixels to inches at any DPI and vice versa. Supports 72, 96, 150, and 300 DPI. Also shows centimeters, millimeters, and points for design work.

## What this calculates

Convert between pixels and inches at any DPI setting. The result depends entirely on DPI: 300 pixels at 96 DPI (web) is 3.125 inches, but at 300 DPI (print) it is just 1 inch. This calculator also shows centimeters, millimeters, and typographic points.

## Inputs

- **Pixels** (px) — min 0 — Enter the dimension in pixels.
- **DPI (Dots Per Inch)** (dpi) — min 1, max 4800 — Dots per inch. Web default is 96; print is usually 300.
- **Convert** — options: Pixels → Inches, Inches → Pixels

## Outputs

- **Inches** (in) — The dimension in inches.
- **Pixels** (px) — The dimension in pixels.
- **Centimeters** (cm) — The dimension in centimeters.
- **Millimeters** (mm) — The dimension in millimeters.
- **Points (pt)** (pt) — The dimension in typographic points (1 pt = 1/72 inch).

## Details

Pixels are a digital unit with no fixed physical size. The physical size depends on the resolution (DPI, or dots per inch) of the output device.

**The Formula:**

- Inches = Pixels / DPI
- Pixels = Inches x DPI

**Common DPI Values:**

| DPI | Typical Use |
|-----|-------------|
| 72 | Classic Mac screen resolution |
| 96 | Windows default screen resolution |
| 150 | Low-quality print |
| 300 | Standard print quality |
| 600 | High-quality print |
| 1200+ | Professional photo printing |

**Pixels to Inches at Common DPIs:**

| Pixels | 72 DPI | 96 DPI | 150 DPI | 300 DPI |
|--------|--------|--------|---------|--------|
| 100 | 1.39" | 1.04" | 0.67" | 0.33" |
| 300 | 4.17" | 3.13" | 2.00" | 1.00" |
| 600 | 8.33" | 6.25" | 4.00" | 2.00" |
| 1080 | 15.00" | 11.25" | 7.20" | 3.60" |
| 1920 | 26.67" | 20.00" | 12.80" | 6.40" |

**Practical tip for print design:** If you want a 4x6 inch photo at 300 DPI, you need an image that is 1200 x 1800 pixels. Lower resolution images will look pixelated when printed at larger sizes.

## Frequently Asked Questions

**Q: How do I convert pixels to inches?**

A: Divide the pixel value by the DPI (dots per inch). For example, 600 pixels at 300 DPI = 600 / 300 = 2 inches. At 96 DPI (web), 600 pixels = 6.25 inches. The DPI makes all the difference.

**Q: What DPI should I use for web vs. print?**

A: For web and screen display, 96 DPI is the standard on Windows (72 on Mac). For print, use at least 300 DPI for photos and detailed graphics. Text can sometimes get away with 150 DPI, but 300 is the safe standard for professional results.

**Q: What is the difference between DPI and PPI?**

A: DPI (dots per inch) technically refers to a printer's output resolution, while PPI (pixels per inch) refers to screen or image resolution. In practice, most people and software use the terms interchangeably. This calculator works for both.

**Q: How many pixels are in one inch?**

A: It depends on the DPI. At 96 DPI, one inch is 96 pixels. At 300 DPI, one inch is 300 pixels. There is no universal answer because a pixel has no inherent physical size.
