Display a metric in big bold font, with an optional indicator of how the metric changed.

Tip: If you want to display a large number, it may be a good idea to shorten it using packages like millify or numerize. E.g. 1234 can be displayed as 1.2k using st.metric("Short number", millify(1234)).

Function signature[source]

st.metric(label, value, delta=None, delta_color="normal", help=None, label_visibility="visible")


label (str)

The header or title for the metric. The label can optionally contain Markdown and supports the following elements: Bold, Italics, Strikethroughs, Inline Code, Emojis, and Links.

This also supports:

  • Emoji shortcodes, such as :+1: and :sunglasses:. For a list of all supported codes, see https://share.streamlit.io/streamlit/emoji-shortcodes.
  • LaTeX expressions, by wrapping them in "$" or "$$" (the "$$" must be on their own lines). Supported LaTeX functions are listed at https://katex.org/docs/supported.html.
  • Colored text, using the syntax :color[text to be colored], where color needs to be replaced with any of the following supported colors: blue, green, orange, red, violet, gray/grey, rainbow.

Unsupported elements are unwrapped so only their children (text contents) render. Display unsupported elements as literal characters by backslash-escaping them. E.g. 1\. Not an ordered list.

value (int, float, str, or None)

Value of the metric. None is rendered as a long dash.

delta (int, float, str, or None)

Indicator of how the metric changed, rendered with an arrow below the metric. If delta is negative (int/float) or starts with a minus sign (str), the arrow points down and the text is red; else the arrow points up and the text is green. If None (default), no delta indicator is shown.

delta_color ("normal", "inverse", or "off")

If "normal" (default), the delta indicator is shown as described above. If "inverse", it is red when positive and green when negative. This is useful when a negative change is considered good, e.g. if cost decreased. If "off", delta is shown in gray regardless of its value.

help (str)

An optional tooltip that gets displayed next to the metric label.

label_visibility ("visible", "hidden", or "collapsed")

The visibility of the label. If "hidden", the label doesn't show but there is still empty space for it (equivalent to label=""). If "collapsed", both the label and the space are removed. Default is "visible". This argument can only be supplied by keyword.


import streamlit as st

st.metric(label="Temperature", value="70 °F", delta="1.2 °F")

st.metric looks especially nice in combination with st.columns:

import streamlit as st

col1, col2, col3 = st.columns(3)
col1.metric("Temperature", "70 °F", "1.2 °F")
col2.metric("Wind", "9 mph", "-8%")
col3.metric("Humidity", "86%", "4%")

The delta indicator color can also be inverted or turned off:

import streamlit as st

st.metric(label="Gas price", value=4, delta=-0.5,

st.metric(label="Active developers", value=123, delta=123,
