Use a font identification tool such as WhatTheFont, FontSquirrel Matcherator, or Adobe Capture
Upload the image to the tool
Crop the text area tightly around the letters
Make sure the text is clear, straight, and high resolution
Compare the suggested fonts with the image
Check the font style, weight, spacing, and letter shapes
Use image editing software to zoom in on individual letters
Search manually by matching distinctive characters like a, g, R, and Q
Test candidate fonts by typing sample text and comparing it to the image
Look for font families with similar serifs, strokes, and proportions
If needed, ask in font identification communities or forums
