Logo Size Guide
This logo size guide gives you the right dimensions for your logo everywhere it appears: your website header, your favicon, social media profiles and banners, your email signature, and your printed business cards. Pick a platform below for its recommended size, or use the scaler to resize any logo without stretching it.
1. Find a recommended logo size
Upload at least the recommended size — a smaller file gets stretched and looks blurry.
2. Scale a logo to a new size
Fill in the width or the height; if both, the width is used.
Common aspect ratios, at scale
Wide logos suit headers and banners; square logos suit profile pictures.
A 3:1 banner is three times as wide as it is tall — the shape of an X header at 1500 × 500 px. A 1:1 square is the shape of nearly every profile picture.
How it works
The platform picker works from a short list of recommended sizes. Choose the platform — Facebook, Instagram, X, LinkedIn, YouTube, TikTok, Pinterest, your website, email, or print — then choose where the logo will appear, such as a profile picture, a cover image, or a header. The tool shows the recommended dimensions in pixels, the aspect ratio, and a file-format tip. Profile pictures are almost always square, a 1:1 ratio, while covers and banners are wide: the X header is 1500 × 500 px, a 3:1 ratio, and YouTube channel art is 2560 × 1440 px, a 16:9 ratio. The format tip matters too: a logo with a transparent background should be a PNG or an SVG.
Aspect ratio is the shape of an image, written as width compared to height. A square image is 1:1 because both sides are equal. A logo that is 1200 px wide and 800 px tall is 3:2, because both numbers divide by 400 to give 3 and 2. The ratio never changes when you resize correctly: a 3:2 logo stays 3:2 whether it is 1200 × 800 px on a website or 300 × 200 px in an email signature. Change the width without matching the height and the logo stretches — circles become ovals and text looks wrong.
The scaler does the resizing math for you. Enter the original width and height, then enter the target width or the target height — whichever side you know. The tool keeps the aspect ratio fixed and works out the other side. With a target width, it divides the target width by the original width to find the scale factor, then multiplies the original height by that factor. With a target height, it works the other way round. Results are rounded to whole pixels.
New width = target height × (original width ÷ original height)
Two practical rules sit behind all the numbers on this page. First, always start from the largest version of your logo you have. Shrinking a large logo keeps it sharp, but enlarging a small one makes it soft and blurry. Keep a master copy at least 2000 px on its longest side — or better still a vector file — and export smaller copies from it for each platform. Second, remember that platforms crop and compress: profile pictures are often shown as circles, so keep text away from the corners, and keep the important part of a banner in the middle. Print follows a different rule: a business card is 3.5 × 2 inches, and at the standard print quality of 300 dpi it needs an image of 1050 × 600 px. For print, use a vector file such as SVG, EPS, or PDF when you can, because vectors have no pixels to run out of.
Worked example
Say you run a small bakery and your logo file is 1200 × 800 px. You want to use it in your email signature, where it should be 300 px wide.
Step 1: The original size is 1200 × 800 px, an aspect ratio of 3:2, since both numbers divide by 400. Enter 1200, 800, and 300 in the original width, original height, and target width boxes, leaving target height blank.
Step 2: The scale factor is 300 ÷ 1200 = 0.25, so the new height is 800 × 0.25 = 200.
Step 3: Read the result: the scaled logo is 300 × 200 px.
The tool shows exactly that: 300 × 200 px, aspect ratio 3:2, scaled from 1200 × 800 px. The ratio is unchanged, so nothing is stretched — and the same steps work in reverse with a target height.

FAQ
What size should my logo be for a website header?
A header logo around 250 by 100 pixels works well for most sites: wide enough to read clearly, short enough to keep the header slim. Use a transparent PNG or an SVG, and keep the original larger than the displayed size so it stays sharp on high-resolution screens.
What is the best file format for a logo?
SVG is best for websites because it scales to any size without losing sharpness. PNG is best when you need transparency, such as a logo over a photo. JPG has no transparency and loses quality each time it is saved. For print, use a vector file such as SVG, EPS, or PDF, or a PNG at 300 dots per inch.
Why does my logo look blurry on social media?
A logo looks blurry when the uploaded file is smaller than the size the platform displays, because the platform stretches it to fit. Upload a file at least as large as the recommended size — 400 by 400 pixels for an X or LinkedIn profile picture — and keep the important parts inside the center, since profile pictures are often cropped into a circle.
How do I resize a logo without stretching it?
Change only one side and let the other follow the aspect ratio: set a 1200 by 800 pixel logo to 300 pixels wide and the height becomes 200 pixels. The scaler on this page does that math for you.
Do these recommended logo sizes change over time?
Yes, platforms change their recommended sizes from time to time, so treat this page as a guide rather than a fixed rule. Check the platform's own help pages before a big launch, and always keep a large, high-quality master copy of your logo so you can export a fresh size whenever a recommendation changes.
