--- title: "Ultimate Bold Icons Set - 19037 customizable PNGs, SVGs, PDFs" product: "Streamline Icons, Illustrations and Elements" url: /icons/streamline-bold canonical_url: "https://www.streamlinehq.com/icons/streamline-bold" summary: "Solid opaque fills with transparent cutouts and rounded outer silhouettes, monochrome — the highest-weight Ultimate sub-style. Notably harder and more serious than its line-weight siblings despite sharing the same rounded geometry. The tone signals confidence and directness: solid visual weight that reads as active, selected, or primary without requiring colour. Best for active states, mobile tab bars, badges, dark-mode-first products, and any context requiring maximum legibility at 12–16px; best used as the emphasis layer alongside Regular rather than as the sole icon weight." --- # Ultimate Bold Icons Set - 19037 customizable PNGs, SVGs, PDFs Bold style features strong, solid shapes for instant recognition.

It is among the hardest sub-styles in the catalog — solid shapes represent the highest visual weight in the family and are unmistakably hard. It is somewhat formal — heavy fills read as authoritative and direct, with rounded silhouettes preventing full formality. It is one of the more serious sub-styles in the catalog — strong graphic weight signals seriousness with no decorative elements. On its human↔mechanical character, it is somewhat mechanical — rounded outer shapes retain some human quality while the density of fill reads as systematic. --- ## Pairing & Compatibility ### Typography pairing - **Primary**: Archivo Black / Space Grotesk Bold — matches the visual weight of solid icons - **Display**: Syne, Clash Display — adds graphic boldness in marketing contexts - **Body**: Inter Regular — provides contrast between the heavy icon and light body text - **Avoid**: Ultra-thin or hairline fonts — the visual weight imbalance is extreme and reads as unresolved ## Example icons - [Bird House](https://assets.streamlinehq.com/image/private/w_34,h_34,ar_1/f_auto/v1/icons/home/bird-house-zvq6y48k9kk8eskmht27vb.png/bird-house-mul52ur5opf1nunlmz6vrr.png?_a=DATAiZkSZAA0) - [House](https://assets.streamlinehq.com/image/private/w_34,h_34,ar_1/f_auto/v1/icons/home/house-tbxba4tp0peu28jvxc57sc.png/house-sw73n4cvcmlxyhlvnn7p.png?_a=DATAiZkSZAA0) - [House 2](https://assets.streamlinehq.com/image/private/w_34,h_34,ar_1/f_auto/v1/icons/home/house-2-9ls4g5fs1morqjtvlttgk9.png/house-2-g8ttum2r47nw9cz9bx0fgn.png?_a=DATAiZkSZAA0) - [House 2 Alternate](https://assets.streamlinehq.com/image/private/w_34,h_34,ar_1/f_auto/v1/icons/home/house-2-alternate-y993yn2wsnfvq1yuywheq.png/house-2-alternate-htv083q2fkct5dpgl5r7gt.png?_a=DATAiZkSZAA0) - [House 3](https://assets.streamlinehq.com/image/private/w_34,h_34,ar_1/f_auto/v1/icons/home/house-3-9ll2q2rk5fpwyp2zjqipt.png/house-3-iq5wvvukwu7kyzls8puqxn.png?_a=DATAiZkSZAA0) - [House 3 Alternate](https://assets.streamlinehq.com/image/private/w_34,h_34,ar_1/f_auto/v1/icons/home/house-3-alternate-c31949gch4x9hn0z5vjl.png/house-3-alternate-yp53em0ox5bzcumzyvvlgo.png?_a=DATAiZkSZAA0) - [House 4](https://assets.streamlinehq.com/image/private/w_34,h_34,ar_1/f_auto/v1/icons/home/house-4-0jiu11wr0a9axtwqcdk27o.png/house-4-30oexgi40el8j672w7b164.png?_a=DATAiZkSZAA0) - [House Alternate](https://assets.streamlinehq.com/image/private/w_34,h_34,ar_1/f_auto/v1/icons/home/house-alternate-gi6p1imvhqi98x6e07v94u.png/house-alternate-owfo1rps5ai8ujrlcz4s9.png?_a=DATAiZkSZAA0) - [House Chimney](https://assets.streamlinehq.com/image/private/w_34,h_34,ar_1/f_auto/v1/icons/home/house-chimney-s76slg5lnvrxcirmxl9en.png/house-chimney-b7l80rfgiet8gh16imy0ni.png?_a=DATAiZkSZAA0) - [House Chimney 1](https://assets.streamlinehq.com/image/private/w_34,h_34,ar_1/f_auto/v1/icons/home/house-chimney-1-gcqr6bujxwares28bstzjq.png/house-chimney-1-wh01mi2deqhvasp2eypava.png?_a=DATAiZkSZAA0) - [House Chimney 1 Alternate](https://assets.streamlinehq.com/image/private/w_34,h_34,ar_1/f_auto/v1/icons/home/house-chimney-1-alternate-mofuall5b4kj8vzuikcy5h.png/house-chimney-1-alternate-wvmqp51wvisp9p8p7xro2m.png?_a=DATAiZkSZAA0) - [House Chimney Alternate](https://assets.streamlinehq.com/image/private/w_34,h_34,ar_1/f_auto/v1/icons/home/house-chimney-alternate-r4t3oq4indhd7llmvmvbth.png/house-chimney-alternate-x4nsn08vk5pvqvkkwxrt.png?_a=DATAiZkSZAA0) --- [View full sitemap](/sitemap.md)
