How to set the next/image component to 100% height

I have a Next.js app, and I need an image that fills the full height of its container while automatically deciding its width based on its aspect ratio.

I have tried the following:

<Image
    src="/deco.svg"
    alt=""
    layout="fill"
/>

This snippet compiles successfully, but on the frontend, I see the following error:

Error: Image with src "/deco.svg" must use "width" and "height" properties or "unsized" property.

This confuses me because according to the docs, these properties are not required when using layout="fill".

I have been encountering this one. It's a pain. Here's how I do it.

<Image
  src="/images/logo.png"
  alt="Logo"
  height={0}
  width={150}
  style={{ height: "40px", width: "auto" }}
/>

You can control the height via style={{height: "40px"}} keep the width on style auto.

Just increase the width property for the resolution of the image. width={150} set the height to 0.

I don't to use as it keeps logging warning on browser console.

This fixes it for me:

const imageStyle = {
   width: '100%',
   height: 'auto',
  }
     
export default function ProfileImage() {
   return (
       <Image 
           src="..." 
           width={100} 
           height={0} 
           style={imageStyle} /> // The style attribute fixes the issue
  }

  <div className="relative h-full w-full">
           <Image

                objectFit="cover"

With Next.js 13 or above version, you can try like this.

<div className="b relative h-[300px] w-full overflow-hidden rounded-lg" key={idx}>
    <Image fill src={src} alt='img' className="w-full object-cover" />
</div>

Update2024: Next 14.6

To make a Image take full height and width of parent add a div wrapper with position relative along with fill = { true} in next Image

Working example:

<div style={{
                    position: "relative",
                    width: "100%",
                    height: "100%",
                }}>
                    <Image
                        src={project.image_url}
                        alt={`Cover Image for ${project.name} `}
                        style={{ objectFit: "cover" }}
                        loading="lazy"
                        fill = { true}
                    />
                </div>

As of Next.js 13.5, adding layout="responsive" & adding className and styling in the .css file works

<Image
    width={100}
    height={120}
    layout="responsive"
    className="sample_img"
    src="..."
    alt={"Sample Image"}
/>

styles.css file:

.sample_img{
   max-height: 5rem;
   aspect-ratio: 1;
}

Once the css is loaded the image changes from 100px * 120px to 5rem * 5rem dimensions

Image with auto height and width. This will display actual size of image.

<Image
  src={selectedImage}
  width={0}
  height={0}
  alt=""
  style={{ width: "auto", height: "100%" }} // optional
/>

Image with fixed height and width.

<div style={{ position: "relative", width: "200px", height: "279px" }}>
  <Image
    src={selectedImage}
    fill
    alt=""
    style={{ objectFit: "cover" }}  // As per your requirement
  />
</div>

When you use the layout property with a value of fill, Next.js will automatically set the position: absolute and top:0, left:0, right:0, and bottom:0 CSS properties on the Image component, which makes it fill its container. However, Next.js still needs to know the original dimensions of the image so that it can determine the aspect ratio and resize it accordingly.

You can either provide the width and height properties with the appropriate values, or you can use the unsized property instead, which tells Next.js to use the original dimensions of the image.

<Image  
  src="/deco.svg"
  alt = ""
  layout="fill"
  unsized
 />

In 2023, every above solution is deprecated,

use below

<Image
  src="url"
  width={0}
  height={0}
  sizes="100vw"
  style={{ width: '100%', height: 'auto' }} // optional
/>

And in next v13

       <Image
        src={src}
        width={200}
        height={160}
        alt={alt}
        sizes="(max-width: 768px) 100vw,
              (max-width: 1200px) 50vw,
              33vw"
        style={{ height: '100%', width: '100%' }} //The point is right there!
        //OR className='w-100 h-100'
      />

On Next 13 when getting images from external URLs you can simply pass fill.

import Image from "next/image";

<Image
  src="https://unaqua.com.br/img/logo.png"
  fill
/>

<Image
    src="/deco.svg"
    alt=""
    width={1000}
    height={1000}
    className='nextimg'
/>

in the place where your stylesheet add

.nextimg{
  width: 100%;
  height: auto;
}

BTW I added 1000 for width and height when its small amount image gets unclear. and think you can add your own styles for nextImg class

Maybe these other answers are for a different NextJS version, but none of them worked for me.

I am using NextJS v13.0.0

To accomplish this, I had the following JSX (using TailwindCSS, should be easy to translate to vanilla CSS):

<div className="h-screen relative">
  <Image
   src="/image.png"
   alt="pic of dog"
   fill={true}
  />
</div>

The important part here is making the parent div's position: relative (and setting it's height/width to be what you want for the image) and setting fill={true}. I got this from the NextJS Image documentation:

General image documentation: https://nextjs.org/docs/api-reference/next/image

Documentation on the fill attribute: https://nextjs.org/docs/api-reference/next/image#fill

Hope this helps someone!

For me in Next 13 worked fine after I imported the image and moved it away from public:

Before

<Image src='/link-to-public/img.png' alt="topmoto.pro" />

After

import img from "../assets/img.png";
...
<Image src={img} alt="topmoto.pro" />

If someone use NextJS with styled components. It works:

 const Container = styled.div`
  width: 100%;

  div, span {
    position: unset !important;
  }

  .image {
    object-fit: contain;
    width: 100% !important;
    position: relative !important;
    height: unset !important;
  }
`;

      <Container>
            <Image src={ src }
                   layout="fill"
                   className={ "image" }          
            />
        </Container>

In case you dont want to use absolute values for height and width , that is in px etc , you can do something like this

    <div style={{ position: "relative", width: "100%", paddingBottom: "20%" }} >
  <Image
    alt="Image Alt"
    src="/image.jpg"
    layout="fill"
    objectFit="contain" // Scale your image down to fit into the container
  />
</div>

Here is a way: For example I want to have an image that covers the whole width & height of its container which is a div.

<div className={'image-container'}>
  <Image src={path} layout="fill" className={'image'} />
</div>

And here is the style: (There is a container div that occupies half width & height of viewport & my image will cover it.)

// Nested Styling
.image-container {
    width: 50vw;
    height: 50vh;
    position: relative;

    .image {
        width: 100%;
        height: 100%;
        position: relative !important;
        object-fit: cover; // Optional
    }
}

// Or Normal Styling
.image-container {
    width: 50vw;
    height: 50vh;
    position: relative;
  }
.image-container .image {
    width: 100%;
    height: 100%;
    position: relative !important;
    object-fit: cover; // Optional
}

I think also provide object-fit attribute on the Image element like this:-

<Image
    alt="Mountains"
    src="/mountains.jpg"
    layout="fill"
    objectFit="cover"
  />

Example provided by Nextjs can be https://github.com/vercel/next.js/blob/canary/examples/image-component/pages/layout-fill.js
