Accessing image dimensions on an ImageField in a Django template?

Question

I have ImageField in my model and I'm able to display the image in a template. However, how do I retrieve the image's height and width?

Answer 1

See the documentation for ImageField.

In addition to the special attributes that are available for FileField, an ImageField also has height and width attributes.

So just do the following:

<img src="{{ image.url }}" width="{{ image.width }}" height="{{ image.height }}"/>

Answer 2

In my case, for the width and height fields to work, I need to set the width_field and height_field of the ImageField

E.g.

class Product(models.Model):
    image = models.ImageField(width_field='image_width', height_field='image_height')
    image_width = models.IntegerField()
    image_height = models.IntegerField()
