How did you arrive at the size? Why so small?

I am making a logo to use on Shopify. Frist i tried 148mm*210mm, shopify resized the imaged and it looks pixelated so i made it smaller.

400 x 150 pixels is quite small. At 300 dpi that is 1 1/3 inch by 1/2 inch or 3 cm x 1.25 cm.

I am going to assume that you are using Designer as you used the term drawing. Go to View > View Mode > and choose one of the Pixel choices, now set the zoom to 100 % look at your work.

It looks more pixelated, and the quality of the output still the same (pixelated).
The view mode setting was vector, will that affect my output?

Thank you

400px*150px Same size as the canvas

The canvas size of my drawing is 400px*150px and its 300 DPI. Lines are smooth when i zoomed in close, but its very pixelated when zoomed out and exporting to png.
Is my canvas setup correct? and how can i fix it?

Thank you
