What does an aspect grid look like?

An aspect grid can look like this:

This is the style of aspect grid that you can find at astro.com. It is also sometimes referred to as an aspect table. But, they can also look like this:

The aspect grid style shown above is from the Astro Gold app. Both styles show the same information from the same chart, they just display it in a slightly different way.

How do I read an aspect grid?

Aspect grids can seem pretty overwhelming at first with so many glyphs, columns, and rows. But, once you get the hang of it, it seems simple and offers a lot of information about the angles in the natal chart.

The first aspect grid we are going to look at shows aspects made in a natal chart only.

Natal chart aspect grid

First, we’re going to look at the aspect grid used at astro.com.

First, notice how each planet, the North Node of the moon, Chiron, and the Ascendant and Midheaven are all represented on each stair step going down the right side of the grid. All but the sun are repeated down each row on the left side of the grid.

To find which planets are in aspect, which aspect it is, and the orb, you simply find the rectangle where the planet on the right intersects with the planet on the left. This is much easier to understand with an example!

Let’s say you wanted to find out if Mercury aspects Jupiter and what kind of aspect it would be. (Not sure what all of the symbols mean? There are tables showing what the symbols mean at the end of this article, click here to go there.)

On the right side of the grid, find the glyph for Mercury. Follow that column down until you get to the row that Jupiter is in on the left side of the grid. Where Mercury’s column and Jupiter’s row intersect, it shows that there, in fact, is an aspect.

The symbol there shows it is an opposition. The numbers next to it show the orb of the aspect, or how close the angle is from being a perfect angle. In this opposition, the angle is only 2 degrees and 8 minutes from being a perfect 180° opposition.

Reading the style of grid found in Astro Gold is just as simple!

This time, the grid is square-shaped. All of the planets are listed across the top of the table and down the left side. But, it is read much in the same way.

To find the same Mercury and Jupiter aspect, find Mercury at the top of the grid. Work your way down the table until you come to Jupiter’s row. There, you will see the glyph for opposition and it has an orb of 2 degrees and 8 minutes listed.

Natal chart with transits aspect grid

The planets in our natal charts don’t only make aspects with each other. The current and moving transiting planets can also aspect the planets in our natal charts.

Aspect grids showing angles made between our natal planets and the transiting planets have another layer of information included but are read in a similar fashion.

Above is the natal and transiting planet aspect grid from astro.com. The aspect grid for natal and transiting planets from Astro Gold works just like this one. You can see that it has “nat” next to the planets on the top of the grid, short for “natal,” and “tr” next to the planets along the left side, short for “transits.”

To read aspects in a natal/transiting aspect grid, you follow the same steps as you did when it was just showing natal aspects. Find your natal planet at the top and follow it down until you reach the row of the transiting planet. Where they intersect shows the aspect made and its orb.

You could also start on the left side with a transiting planet and follow it to the right until you get to the column of the natal planet. Either way works.

In the natal and transiting planet aspect grid above, you can see that when this article was made, this individual’s natal Venus was trine transiting (the currently moving) Venus at an orb of 0 degrees and 56 minutes.
