What Resolution Do You Need to Print an A4 Photo at 200 dpi and 300 dpi?

 If you want to print a photo on A4 paper (210 × 297 mm) and keep good print quality, you need to know the correct pixel resolution. Since print resolution is measured in dpi (dots per inch), we first need to convert millimeters to inches.

A4 Size in Inches

• Width: 210 mm ÷ 25.4 ≈ 8.27 inches

• Height: 297 mm ÷ 25.4 ≈ 11.69 inches

1. Required Resolution for A4 at 200 dpi

To calculate the pixel dimensions, multiply each side by 200 dpi:

• Width: 8.27 × 200 ≈ 1654 pixels

• Height: 11.69 × 200 ≈ 2338 pixels

➡️ Required resolution: ~1654 × 2338 px

---

2. Required Resolution for A4 at 300 dpi

For higher-quality printing, multiply by 300 dpi:

• Width: 8.27 × 300 ≈ 2480 pixels

• Height: 11.69 × 300 ≈ 3507 pixels

➡️ Required resolution: ~2480 × 3507 px

Password Security: “I always use the same password for all my accounts...”

 The Problem Description

Many people use the same password for all their accounts because it is easier to remember. However, this practice is very dangerous. If one account is hacked, all your other accounts (email, banking, social media, etc.) can be easily accessed by cybercriminals. This problem is related to cybersecurity and personal data protection.

Name and Definition of the Item

Item: Password reuse
Definition: Password reuse happens when a person uses the same password for more than one account or service. This increases the risk of data breaches and identity theft.
